Description and Uses
Hydrazine sulphate, hydrobromide and hydrochloride have been reported to be occupational sensitizers, mainly in soldering flux.
Hydrazine is a highly reactive base and powerful reducing agent. It acts as an oxygen scavenger and is highly reactive with other chemicals. Hydrazine has a number of uses including, as a chemical precursor to blowing agents (e.g., azodicarbonamide and azobisisobutyronitrile), in the organic synthesis of pharmaceuticals and pesticides (e.g., isoniazid, fluconazole, and 3-amino-1,2,4-triazole), as a missile and rocket propellant (e.g., used in the F-16 fighter), as a gas-forming agent in air bags (e.g., sodium nitrite), as a corrosion inhibitor and reducing agent in large industrial boilers, and as a fuel source in fuel cells.
