6-Hydroxybenzothiazole is one of the organic compounds. Its physical properties are quite characteristic and are described in detail by you.
Looking at its properties, under normal circumstances, 6-hydroxybenzothiazole is mostly white to light yellow crystalline powder. This morphology is easy to identify, and in many chemical operations and applications, its powder shape helps to fully carry out the reaction, because the larger specific surface area allows for more extensive contact between the reactants.
In terms of melting point, the melting point of 6-hydroxybenzothiazole is about 240-244 ° C. Melting point is one of the important physical properties of a substance. This specific melting point range is of great significance in the identification of the compound and in the process involving high temperature treatment. Precise control of the temperature can ensure that the substance maintains a stable state in a specific process and does not decompose or undergo other undesirable changes due to temperature inappropriateness.
Solubility is also its key physical property. 6-Hydroxybenzothiazole is slightly soluble in water. This property is derived from its molecular structure, which has both a relatively hydrophobic benzothiazole ring and a hydrophilic hydroxyl group. However, in general, its hydrophobicity is dominant, so its solubility in water is limited. However, in organic solvents such as ethanol and dimethyl sulfoxide (DMSO), it exhibits good solubility. This solubility characteristic is widely used in chemical synthesis, drug development and other fields. Scientists can choose suitable solvents according to their solubility to promote the reaction process or achieve effective separation and purification.
In addition, 6-hydroxybenzothiazole has certain sublimation properties. Although it is not significant at room temperature and pressure, it can be directly converted from solid to gaseous under specific temperature and pressure conditions. This sublimation characteristic may be used in some special purification processes to achieve effective separation from other impurities.
In summary, the physical properties of 6-hydroxybenzothiazole, such as its properties, melting point, solubility, and sublimation, play a crucial role in its research and application in many fields such as chemistry and medicine. Researchers need to grasp it in detail before making good use of this compound.

The stability of 6-hydroxybenzothiazole depends on many factors. This substance has a unique molecular structure, the benzothiazole ring is combined with a hydroxyl group, and this structure endows it with specific reactivity.
In terms of its stability, under normal conditions at room temperature and pressure, 6-hydroxybenzothiazole can be said to be stable. However, if the environment changes, its properties will also change. In case of high temperature, the bond energy within the molecule is affected, which can cause decomposition or rearrangement reactions. When the temperature rises to a certain extent, the bond between the hydroxyl group or the benzothiazole ring breaks, causing structural changes.
And if it is in a specific chemical environment, such as in a strong acid-base medium, its stability is also challenged. In a strong acid, the hydroxyl group or protonation causes the charge distribution of the molecule to change, which in turn affects its reactivity and stability. Under a strong base, the hydroxyl group or deprotonation becomes a nucleophilic reagent, which easily reacts with other surrounding substances.
In addition, light radiation in some bands may provide energy for molecules, causing electron transitions, and excited molecules are more reactive or undergo photochemical reactions, resulting in reduced stability.
And if 6-hydroxybenzothiazole contains impurities, impurities or interacts with the host molecule, catalyzes or participates in some reactions, it also affects its stability.
In summary, the stability of 6-hydroxybenzothiazole is not absolute and is often affected by factors such as temperature, acid and base, light and impurities. To determine its stability, it must be studied carefully according to the specific environment and conditions.

The synthesis methods of 6-hydroxybenzothiazole are as follows.
One is to use o-aminophenol and ammonium thiocyanate as starting materials. In an appropriate reaction vessel, mix o-aminophenol and ammonium thiocyanate in a certain proportion, and add an appropriate amount of solvent, such as ethanol or water, to promote the contact and reaction of the two. Subsequently, under heating conditions, the two condensation reaction occurs. The heating temperature needs to be strictly controlled, generally between 100-150 ° C. Within this temperature range, the amino group of o-aminophenol interacts with the thiocyanyl group of ammonium thiocyanate to gradually form the cyclic structure of benzothiazole, and at the same time removes a molecule of ammonia. After this reaction process, 6-hydroxybenzothiazole can be obtained.
The second is to use 2-mercaptobenzothiazole as raw material for oxidative hydroxylation. Take 2-mercaptobenzothiazole and place it in the reaction system, add a suitable oxidant, such as hydrogen peroxide or potassium permanganate. Taking hydrogen peroxide as an example, in an appropriate solvent (such as acetic acid, etc.), hydrogen peroxide acts as a hydroxylation reagent. At a certain temperature and in the presence of a catalyst (such as some transition metal salts), its peroxide bond breaks, and one oxygen atom attacks a specific position in the benzene ring of 2-mercaptobenzothiazole, introduces a hydroxyl group, and then converts to 6-hydroxybenzothiazole. In this process, the temperature is controlled at 50-80 ° C, and the amount of catalyst needs to be precisely prepared to make the reaction efficient.
The third can be prepared by the reaction of o-halogenated phenol with thiourea. Put o-halogenated phenol (such as o-chlorophenol or o-bromophenol) and thiourea into a reactor according to a certain stoichiometric ratio, and add an appropriate amount of basic reagents, such as sodium hydroxide or potassium carbonate, to promote the reaction. Under heating and organic solvent (such as N, N-dimethylformamide, etc.) environment, the halogen atom of o-halogenated phenol undergoes nucleophilic substitution reaction with the amino group of thiourea, and then goes through steps such as intramolecular cyclization, and finally generates 6-hydroxybenzothiazole. The heating temperature of this reaction is about 120-160 ° C. The amount of basic reagents and the reaction time have a significant impact on the yield of the product.

The price of 6-hydroxybenzothiazole in the market often fluctuates due to a variety of reasons. According to the laws recorded in Tiangong Kaiwu and looking at the market conditions of various materials, the price of 6-hydroxybenzothiazole also changes according to the world.
In the past, the price of the city was often based on quality and supply and demand. Those with high quality will definitely be expensive; if the supply exceeds the demand, the price may decline; if the supply exceeds the demand, the price will rise. If you taste the price, it is about tens of yuan to hundreds of yuan per gram. However, this is only a rough number, and it is difficult to stick to one grid.
The change of the city is also unpredictable in an instant. The current market may be different from the past due to the production of raw materials, the new technology, and the regulations of the government. And the cities of various places are also different. To know the exact price, when you visit various chemical raw material markets in person, or consult the franchised merchants, you can get the real price of the present. Do not take old news as the accuracy, but observe the changes in the times.
