This diazo compound is decomposed by caustic alkalis with the formation of cyanamide and hydrazoic acid, CH4N5�NO3 = N3H + CN�NH2 + HNO3, whilst acetates and carbonates convert it into amidotetrazotic acid, Amidotetrazotic acid yields addition compounds with amines, and by the further action of nitrous acid yields a very explosive derivative, diazotetrazol, CN6.

Azoimide, or Hydrazoic Acid, N3H, is an acid liquid of disagreeable odour, producing headache if inhaled.

AZOIMIDE, or Hydrazoic Acid, N3H, a compound of nitrogen and hydrogen, first isolated in 1890 by Th.

An improved method of preparation was found in the use of hippuric acid, which reacts with hydrazine hydrate to form hippuryl hydrazine, C6H5CONH�CH2CONH�NH2, and this substance is converted by nitrous acid into diazo-hippuramide, C6H5CONH�CH2�CO�NH�N2�OH, which is hydrolysed by the action of caustic alkalis with the production of salts of hydrazoic acid.
