2-Chloro-6-methoxybenzothiazole is one of the organic compounds. Its physical properties are quite important and relevant to its many applications.
Looking at its appearance, it is mostly white to light yellow crystalline powder at room temperature, which can help to identify it preliminarily. Its melting point is within a certain range, about 82-84 ° C, and the melting point is stable, which is one of the important indicators for the identification of this compound. Because the melting point is often specific for pure compounds, if impurities are mixed, the melting point may change.
Furthermore, its solubility is also a key physical property. In organic solvents, such as ethanol and acetone, 2-chloro-6-methoxybenzothiazole exhibits some solubility, but in water, the solubility is very small. This difference in solubility is due to its molecular structure characteristics. Its molecules have both hydrophobic parts, so they are more soluble in organic solvents with weaker polarities.
In addition, the density of this compound also has a specific value, about 1.408g/cm ³. As an inherent property of matter, density has important reference value in many chemical operations, such as separation and mixing. The physical properties of 2-chloro-6-methoxybenzothiazole, such as appearance, melting point, solubility, and density, each have their own uses and are indispensable factors for chemical production and scientific research.

2-Chloro-6-methoxybenzothiazole is an organic compound that has attracted much attention in the field of organic synthesis. This substance often has a solid appearance and has specific physical and chemical properties.
From the perspective of chemical activity, its chlorine atom has high reactivity. This chlorine atom is susceptible to attack by nucleophiles and undergoes nucleophilic substitution. For example, if it reacts with alcohols in the presence of bases, the chlorine atom may be replaced by an alkoxy group to form a corresponding ether derivative. The mechanism of this reaction is that the base captures the hydrogen of the alcohol hydroxyl group to form an alcohol negative ion. The negative ion acts as a nucleophilic agent to attack the carbon atom connected to the chlorine atom on the benzothiazole ring, and the chloride ion leaves to complete the substitution reaction.
Furthermore, although the methoxy group is relatively stable, it can also affect the electron cloud distribution of the molecule. Methoxy group is the power supply group, which can increase the electron cloud density on the benzothiazole ring, especially the ortho and para-position. This makes it easier for the electrophilic reagent to attack the ortho and para-position of the methoxy group when the compound is undergoing electrophilic substitution reaction. For example, in the nitration reaction, the nitro group is more inclined to enter the ortho or para-position of the methoxy group.
In addition, the benzothiazole ring itself has a certain aromaticity, which gives the compound a certain stability. However, due to the presence of chlorine and methoxy substituents on the ring, its aromaticity will also be fine-tuned to a certain extent. This fine-tuning will affect the spectral properties of the compound, such as the unique absorption peak or signal in the infrared spectrum, nuclear magnetic resonance spectrum, etc., which can be used to identify and analyze its structure.
In the selection of chemical reaction conditions, because the reactivity of 2-chloro-6-methoxybenzothiazole is related to the characteristics of the substituent, the reaction temperature, reaction time and the proportion of reactants need to be precisely adjusted according to the specific reaction type. For example, in nucleophilic substitution reactions, if the temperature is too high or the side reactions increase, if the temperature is too low, the reaction rate will be slow. Therefore, the best reaction conditions need to be experimentally explored to achieve efficient and highly selective organic synthesis.

The synthesis of 2-chloro-6-methoxybenzothiazole is an important topic in the field of organic synthesis. There are several common methods for the synthesis of this compound.
First, 2-amino-6-methoxybenzothiazole is used as the starting material. First, 2-amino-6-methoxybenzothiazole is reacted with suitable chlorinated reagents, such as thionyl chloride and phosphorus oxychloride, under appropriate reaction conditions. In the reaction, the chlorine atom of the chlorinated reagent will replace the amino group to form 2-chloro-6-methoxybenzothiazole. This reaction needs to control the reaction temperature, reaction time and the ratio of reactants. If the temperature is too high or the reaction time is too long, it may cause side reactions and affect the purity and yield of the product. Generally speaking, the reaction temperature can be controlled in a moderate range, such as 50-80 ° C. The reaction time depends on the specific situation, about a few hours to ten hours.
Second, start from 2-hydroxy-6-methoxybenzothiazole. Use halogenation reaction to achieve chlorination of hydroxyl groups. Chlorine-containing halogenated reagents, such as phosphorus pentachloride, can be selected. In suitable solvents, such as dichloromethane, chloroform, etc., the reaction is carried out. This reaction process also needs to pay attention to the control of reaction conditions. The choice of solvent has an impact on the reaction rate and product distribution. Polar solvents such as dichloromethane can promote the reaction, but at the same time, it may also lead to the formation of impurities. Therefore, it is necessary to fine-tune the reaction conditions, such as controlling the reaction temperature at 0-30 ° C, to ensure the smooth progress of the reaction and improve the yield of the target product.
Third, using 6-methoxybenzothiazole as raw material, the halogenation reaction is carried out first. By selecting the appropriate halogenating agent and reaction conditions, the second position of the benzothiazole ring is introduced into the chlorine atom. This process can improve the selectivity and rate of the reaction with the help of catalysts. For example, a specific metal salt catalyst is selected to promote the halogenation reaction under light or heating conditions. However, this method has high requirements on reaction equipment and operation, and is easy to produce by-products such as polyhalogenation due to high halogenation reactivity. It is necessary to precisely control the amount of halogenating agent, reaction temperature and reaction time to obtain the ideal 2-chloro-6-methoxybenzothiazole product.

2-Chloro-6-methoxybenzothiazole is on the market, and its price range is difficult to determine. The price of this chemical often varies due to various factors, such as the state of supply and demand, the difficulty of the production method, the price of raw materials, and the influence of current situations and policies.
Looking at the market conditions in the past, the price fluctuates quite a lot. When supply and demand are balanced and the production method is relatively easy and the raw materials are abundant, the price may be slightly lower, per kilogram or in the hundreds of yuan. However, if the raw materials are scarce, or the production is limited due to policies, the supply will decrease, and if the demand does not decrease but increases, the price will rise, or more than 1,000 yuan per kilogram, or even higher.
Furthermore, different quality grades and different sources of supply have different prices. For high purity, the price is often higher than that of ordinary ones. And for large factories, the quality is stable and the price may be higher than that of ordinary manufacturers.
Due to the rapidly changing market conditions, if you want to know the exact price range, you must often look at the dynamics of the chemical market and consult suppliers to get a closer number.
