Hydrazine hydrate is a strong reducing agent, which is a raw material for medicines, pesticides, dyes, foaming agents, imaging agents and antioxidants; it is widely used as a deoxidizer for large boiler water; it is also used to manufacture high-purity metals, synthetic fibers, and rare Separation of elements. In addition, hydrazine hydrate is also used to make rockets and explosives. Also used as an analytical reagent. Most of the anthracene derivatives used as a blowing agent are azodicarbonamide, as well as bismuth mesylate and the like. Hydrazine hydrate is used as a derivative of medicine, and isoniazid, fenyl thiosemicarbazide and benzenesulfonyl thiosemicarbazide, as well as antipsychotic drug 1-isonicotinoyl-2-isopropyl hydrazine, anti-psychotic The cancer drug aldehyde-based hydrazine derivative, the anti-infective drug 5-nitrofuran methyl hydrazine derivative, the antibiotic oxazoline cephalosporin, the diuretic antihypertensive drug hydralazine, the antitumor drug methyl phenyl hydrazine and the like. The hydrazine derivative used as a pesticide for hydrazine hydrate is a plant growth regulator maleic hydrazide derivative, a rodenticide two rat nitrophenyl hydrazine, an insecticidal azole pyrazole derivative and a 5-nitrofuran thiourea. , herbicide aminotriazole and the like. In Japan, more than one-third of the use of cockroaches is used as an oxygen scavenger for boiler water, and the liver for foaming agents (including hydrazine hydrate and barium sulphate) accounts for about 30%, and for scorpion medicinal drugs accounts for 10%.
