2-MERCAPTO-5-CHLOROBENZOXAZOLE - Introduction
It is an organic compound with the chemical formula C7H4BrNS2. It is a white crystal or crystalline powder with a special sulfur smell.
It is an important chemical intermediate and has a wide range of uses in industry. It is mainly used for synthetic rubber processing aids (such as rubber antioxidants), pharmaceutical intermediates and dyes and other chemicals.
The method of preparation is generally obtained by bromination of thiobenzothiazole. First, thiobenzothiazole is dissolved in methylene chloride or other solvent, and then sodium bromate or bromite is added. After a period of reaction, the product is obtained by filtration and cooling crystallization.
When using and storing, pay attention to the following safety precautions:
1. The compound is irritating to the skin, eyes and respiratory tract, and should wear appropriate protective equipment, such as gloves, goggles and protective masks.
2. avoid inhalation of aerosol or dust, avoid direct contact with the skin.
3. storage should be placed in a dry, cool place, away from the fire and other flammable materials.
4. Waste disposal shall comply with local laws and regulations, and shall not be discharged or dumped into the environment at will.
Please note that since this is a chemical, more detailed and specific information should be obtained by consulting the relevant professional or referring to the chemical's safety data sheet before using the chemical.
