Metabolite Identification
Common NameHydroxylamine
DescriptionHydroxylamine, also known as [NH2OH] or H2NHO, belongs to the class of inorganic compounds known as homogeneous other non-metal compounds. These are inorganic non-metallic compounds in which the largest atom belongs to the class of 'other non-metals'. Hydroxylamine exists as a solid, possibly soluble (in water), and a strong basic compound (based on its pKa) molecule. Hydroxylamine exists in all living organisms, ranging from bacteria to humans.
