Les hydroxylamines sont les composés dont la formule est -NR1R2-OH elles dérivent de l'hydroxylamine de formule NH2OH.Les hydroxylamines sont aussi des outils chimique utile pour des coupures spécifique de peptides , ils rompent la liaison entre une asparagine (N/asn) et une glycine (G/gly)
Les hydroxylamines ont très souvent un tautomère oxime (cétoxime ou aldoxime si R1 ou R2 = H).
