It is important fine chemical product and intermediate for organic synthesis, with wide use in pharmaceutical, aromatizer, pesticide, electroplating and liquid crystal industries. In pharmaceutical industry, it can be used to synthesize intermediates of sulfonamides such as broad-spectrum sterilization synergist TMP, ampicillin and semi-synthesized penicillin (oral) as well as intermediate of d-(-)-p-hydroxy phenyl picramate. In aromatizer industry, it is mainly used in raspberry ketone, methyl vanillin, ethyl vanillin, anisic aldehyde and nitrile aromatizer. In pesticide industry, it is mainly used to synthesize new-type insecticide, herbicide, o-bromobenzonitrile and hydroxyl casoron. In electroplating industry, it can be used as a new-type cyanogens-free electroplating brightener. |
