hydroxylamine

(NH2OH), an oxygenated derivative of ammonia, used in the synthesis of oximes from aldehydes and ketones. Oximes are reduced easily to amines, which are used in the manufacture of dyes, plastics, synthetic fibres, and medicinals; the oxime of cyclohexanone can be converted to its isomer epsilon-caprolactam, from which nylon-6 is made. Hydroxylamine and its inorganic salts are powerful reducing agents used in the preparation of polymers and as constituents of photographic developers
