in the production of rubber and medicine. This product is a tail-reducing agent to reduce the adsorption of active on the surface of the gas chromatography carrier. Silylation reagent, can be used for cilicamycin in production. Hexamethyldisilazane is an amikacin medicinal intermediate, a protective agent for hydroxyl and amino groups; special organic synthesis. The silylation of amikacin, penicillin, cephalosporin, fluorouracil and various penicillin derivatives during the synthesis process. Surface treatment of diatomite, white carbon black, titanium and other powders. A bonding aid for photoresists in the semiconductor industry. It is a medicinal intermediate of amikacin and a protective agent for hydroxyl and amino groups.
Matters needing attention:
1. When storing, do not allow contact with open flames, keep ventilated and dry to prevent sunlight, storage temperature -50 ℃-45 ℃.
2. When transporting, avoid collision, rain and sunlight. Store and transport as dangerous goods.
3. The product is easily hydrolyzed to silicon ether under neutral or weakly alkaline conditions, and is relatively stable under strong alkali. It is susceptible to violent reactions when encountering acidic substances. In the temperature range of 208~308K, hexamethyldisilazane The rate of hydrolysis accelerates with increasing temperature. Should be kept in a closed container.
