This form is conducive to its full participation in various chemical reactions, and is easy to store and transport. < Br > - ** Melting point and boiling point **: The melting point is between 86 and 88 ° C. At this temperature, the substance gradually melts from solid to liquid, and the intermolecular force changes. The boiling point is about 277.4 ° C. When this temperature is reached, the liquid quickly turns into a gaseous state. The specific melting point and boiling point enable precise temperature control in separation, purification and synthesis to ensure that the reaction proceeds as expected.
- ** Solubility **: This substance is insoluble in water, and its solubility in water is very small. Due to its large difference in molecular polarity from water molecules, it interacts weakly. However, it is easily soluble in common organic solvents, such as dichloromethane, chloroform, N, N-dimethylformamide (DMF), etc. In dichloromethane, it can be rapidly dispersed and dissolved to form a homogeneous solution, which provides convenience for organic synthesis. Because many organic reactions are carried out in organic solvents, it can ensure that the reactants are fully contacted and accelerate the reaction process.
- ** Odor and density **: 3-chloro-benzo [D] isothiazole has a weak special odor. Although it is not strongly pungent, it has a unique smell. The density is about 1.48 g/cm ³, which is relatively large, indicating that the number of molecules in a unit volume is large and the molecular arrangement is close.
The physical properties of 3-chloro-benzo [D] isothiazole mentioned above are of great significance for its research and application. According to the melting point and boiling point, suitable separation and purification methods can be selected; solubility helps to screen suitable reaction solvents; appearance, odor and density provide reference for storage, transportation and use safety. In-depth understanding of these properties can better play its role in chemical, pharmaceutical and other fields.

3 - CHLORO - BENZO [D] ISOTHIAZOLE is one of the organic compounds. The stability of its chemical properties is related to many aspects.
This compound contains the core structure of benzoisothiazole, and there are chlorine atoms connected to the third position of the benzene ring. From the perspective of chemical bonds, the benzene ring has a conjugated large π bond, which gives it a certain stability. The large π bond delocalizes the electron cloud, reduces the energy of the molecule, and stabilizes the structure of the benzene ring. The chlorine atom is connected to the benzene ring, and the electronegativity of chlorine is relatively large. Although it forms a sigma bond with the benzene ring, it will affect the distribution of the electron cloud of the benzene ring due to its electron-absorbing induction effect. However, the conjugated system of the benzene ring is strong, buffering the electron-absorbing action of the chlorine atom to a certain extent, so that the overall structure remains relatively stable.
In terms of chemical reactivity, 3-CHLORO - BENZO [D] ISOTHIAZOLE usually does not easily occur due to the stability of the benzene ring. However, the chlorine atoms on the benzene ring can participate in nucleophilic substitution reactions. Due to the electron absorption of the chlorine atom, the density of the electron cloud in the adjacent and para-position of the benzene ring is relatively reduced, and the nucleophilic reagents are easy to attack this position. However, such reactions require suitable reaction conditions, such as suitable solvents, bases and temperatures, to proceed smoothly.
In terms of thermal stability, under normal conditions, its structure is stable within a moderate temperature range. However, when the temperature is too high, the vibration of chemical bonds intensifies, or some bonds break, triggering decomposition reactions.
Overall, 3-CHLORO-BENZO [D] ISOTHIAZOLE has certain chemical stability under conventional conditions, but under specific reaction conditions or extreme environments, its chemical properties may change and participate in the corresponding chemical reactions.

3-Chloro-benzo [d] isothiazole requires careful attention in many aspects during the production process.
First, it is related to the selection of raw materials. It is necessary to choose high-purity raw materials to ensure the quality of the product. Excessive impurities in the raw materials are prone to side reactions, which not only reduce the yield of the product, but also may affect the purity of the product. For example, when going into battle, only good food and grass can ensure the combat strength of the army, and the raw materials are the "food and grass" for production.
Second, the control of the reaction conditions is crucial. Temperature, pressure, reaction time, etc., will all affect the reaction process and product formation. If the temperature is too high or too low, or the reaction rate is out of control, and improper pressure will also affect the reaction balance. This is like cooking a delicious dish. If the heat and duration are not well grasped, the dish will be difficult to taste. If the reaction time is too short, the reaction will not be complete; if it is too long, it may cause an overreaction.
Third, safety protection should not be underestimated. This compound may have certain toxicity and irritation, and comprehensive protective measures should be taken during production. Workers should wear protective clothing, protective gloves and masks to prevent contact with the human body. The production site should also be well ventilated and expel harmful gases in time. This is like being in a dangerous place, and complete defense is required to ensure safety.
Fourth, equipment selection and maintenance should not be ignored. Appropriate equipment needs to be selected according to the reaction characteristics, and regular maintenance is required to ensure the normal operation of the equipment. Poor equipment performance or frequent failures will interfere with the stability of production and affect the quality and output of products. Just like marching in battle, the weapon is sharp and not damaged, so that it can defeat the enemy.
Fifth, quality monitoring runs through the whole process. The whole production process should be monitored in real time, and problems should be detected and adjusted in time. Strict testing of intermediates and final products is required to ensure that quality standards are met. This is the key to ensuring that the product can reach its intended use, just like the checkpoint is controlled layer by layer to prevent defective products from flowing out.

3-CHLORO-BENZO [D] ISOTHIAZOLE, that is, 3-chloro-benzo [D] isothiazole, the price of this product in the market varies for many reasons.
Its price is often subject to supply and demand. If there are many people in the market, and the supply is thin, the price will rise; conversely, if the supply exceeds demand, the price may decline. For example, if at some time, the chemical industry has a large increase in demand for 3-chloro-benzo [D] isothiazole for new product creation, and it is difficult for producers to increase their production for a while, so the supply should not be needed, and its price will rise.
Furthermore, the price of raw materials is also a major factor. If the raw materials required for the production of 3-chloro-benzo [D] isothiazole are expensive and difficult to obtain, the cost will rise, and the price of the market will also rise. If the price of raw materials soars due to changes in origin, natural disasters, etc., the price of the finished product will also rise.
The simplicity of the process is closely related to the cost. If the preparation method is complicated, requires multiple processes, takes a long time, and uses special tools and techniques, the cost will be high, and the price will also be expensive. If the new and simplified process reduces the cost of preparation, the price may decrease.
The location and regulations of the manufacturer also affect its price. Due to the long transportation distance, the transportation cost of distant producers increases, and their prices sold in different places may be higher than those of nearby real estate producers. Large-scale producers have low unit costs or competitive prices due to the benefits of scale.
In summary, the price of 3-chloro-benzo [D] isothiazole in the city can range from tens per unit to hundreds, fluctuating greatly. The industry needs to constantly observe the market conditions, the trend of raw materials and changes in technology to understand the trend of its price.
