To prepare (2Z) -2 -hydrazone-3-methyl-2,3-dihydro-1,3-benzothiazole hydrochloride hydrate, the method is as follows:
First take an appropriate amount of 3-methyl-2,3-dihydro-1,3-benzothiazole-2-one and place it in a clean reaction vessel. This vessel should be dry and well sealed to prevent impurities from mixing.
Then slowly add hydrazine hydrate to it, and the amount should be accurately weighed to ensure that the reaction ratio is appropriate. When adding hydrazine hydrate, the action should be gentle, and the system should be stirred continuously to make the two fully contact.
During the stirring process, a certain temperature should be maintained, generally controlled in a moderate range, such as 50 to 60 degrees Celsius. This temperature range can make the reaction proceed smoothly, and avoid side reactions caused by excessive temperature.
After the reaction continues for a period of time, after the initial product is formed, the reaction system is cooled to room temperature. Subsequently, hydrogen chloride gas is slowly introduced to make the system an acidic environment, which promotes the formation of hydrochloride salts.
When hydrogen chloride gas is introduced, it is necessary to pay close attention to the reaction phenomenon and control the gas flow rate to prevent the reaction from being too violent. After the reaction is complete, white crystals can be seen to precipitate, which is (2Z) -2 -hydrazone-3-methyl-2,3-dihydro-1,3-benzothiazole hydrochloride.
Finally, after appropriate crystallization, filtration, washing, drying and other steps, (2Z) -2 -hydrazone-3-methyl-2,3-dihydro-1,3-benzothiazole hydrochloride hydrate containing crystalline water can be obtained. Careful attention should be paid to each step to ensure the purity and yield of the product.

(2Z) - 2-hydrazinyl-3-methyl-2,3-dihydro-1,3-benzothiazole hydrochloride hydrate, which is a special chemical substance. When storing and using, many points need to be paid attention to.
First of all, it must be placed in a dry place. Because of its certain hygroscopicity, if the environment is humid, it is easy to cause deliquescence, which will affect its purity and quality. Second, it should be stored in a cool place. If the temperature is too high, it may cause the decomposition and deterioration of substances, which will change the chemical properties. Third, ensure that the storage environment is well ventilated. Avoid contact with the air for a long time to prevent oxidation and other reactions from occurring, resulting in changes in properties.
As for use, first of all, the established operating procedures must be strictly followed. Due to its special chemical properties, improper operation or dangerous, such as explosion, generation of harmful gases, etc. Furthermore, protective measures should be taken during use. It is necessary to wear suitable protective equipment, such as gloves, goggles, masks, etc., to prevent the substance from coming into contact with the skin, eyes, or inhaling into the body and causing harm to the human body. At the same time, the place of use should have good ventilation conditions, and timely discharge of possible harmful gases.
