Related to hydroxylamine: Semicarbazide


1. a partially oxidized derivative of ammonia; reacts with carbonyl groups to produce oximes; forms acid salts, for example, hydroxylamine hydrochloride. It is a chemical mutagen that causes deamination of cytosine residues in DNA.
2. Any compound containing RNH-OH.
