99% up by HPLC Benzophenone Hydrazone 5350-57-2

Benzophenone hydrazone is an important raw material for the synthesis of photosensitive materials, spices and medicines, and an intermediate for ultraviolet absorbers, organic pigments and pesticides. In the pharmaceutical industry, in addition to being used in the production of dipipridine, diphenhydramine, etc., benzophenone hydrazone is also an important precursor for the synthesis of cardiovascular drugs cibendazoline. In the synthesis of drugs such as β-lactam inhibitor tazobactam, it is also widely used as the carboxyl protecting group of 6-APA and 7-APA. Benzophenone hydrazone can also be used to prepare diphenyldiazomethane and related compounds. Diphenyldiazomethane is a valuable intermediate in the peptide synthesis process. At the same time, benzophenone hydrazone is also the main raw material for the preparation of indole. Indole can be used to synthesize a variety of drugs, especially the raw material for tryptophan, one of the indispensable amino acids in the human body. Indole is also a component of many spices.
