Hydroxylamines

Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula . The compound exists as hygroscopic colorless crystals. Hydroxylamine is almost always provided and used as either an aqueous solution or, more often, as one of its salts, such as hydroxylammonium sulfate, a water-soluble solid.

Molnupiravir, sold under the brand name Lagevrio, is an antiviral medication that inhibits the replication of certain RNA viruses. It is used to treat COVID19 in those infected by SARS-CoV-2. It is taken by mouth.

'''N-Phenylhydroxylamine' is the organic compound with the formula C6H5NHOH. It is an intermediate in the redox-related pair C6H5NH2 and C6H5NO. N-Phenylhydroxylamine should not be confused with its isomer α-phenylhydroxylamine or O''-phenylhydroxylamine.

Hydroxybenzotriazole (abbreviated HOBt) is an organic compound with the formula . It is a derivative of benzotriazole. It is a white crystalline powder, which as a commercial product contains some water (~11.7% wt as the HOBt monohydrate crystal). Anhydrous HOBt is explosive. It is mainly used to suppress the racemization and to improve the efficiency of peptide synthesis.

Diethylhydroxylamine (DEHA) is an organic compound with the formula (C2H5)2NOH. Strictly, this is N,N-diethylhydroxylamine. It has an isomer, N,O-diethylhydroxylamine with the formula EtNHOEt. Pure N,N-diethylhydroxylamine is a colorless liquid, although it is usually encountered as a colourless-to-yellow solution in water with an amine-like odor.

Pyoverdines (alternatively, and less commonly, spelled as pyoverdins) are fluorescent siderophores produced by certain pseudomonads. Pyoverdines are important virulence factors, and are required for pathogenesis in many biological models of infection. Their contributions to bacterial pathogenesis include providing a crucial nutrient (i.e., iron), regulation of other virulence factors (including exotoxin A and the protease PrpL), supporting the formation of biofilms, and are increasingly recognized for having toxicity themselves.

1-Hydroxy-7-azabenzotriazole (HOAt) is a triazole used as a peptide coupling reagent. It suppresses racemization that can otherwise occur during the reaction.

'''N,O-Dimethylhydroxylamine''' is a methylated hydroxylamine used to form so called 'Weinreb amides' for use in the Weinreb ketone synthesis. It is commercially available as its hydrochloride salt.

chemical compound

Methoxyamine is the organic compound with the formula CH3ONH2. Also called '''O-methylhydroxylamine''', it is a colourless volatile liquid that is soluble in polar organic solvent and in water. It is a derivative of hydroxylamine with the hydroxyl hydrogen replaced by a methyl group. Alternatively, it can be viewed as a derivative of methanol with the hydroxyl hydrogen replaced by an amino group. It is an isomer of N-methylhydroxylamine and aminomethanol.

'''N-Methylhydroxylamine or methylhydroxylamine''' is a hydroxylamine derivative with a methyl group replacing one of the hydrogens of the amino group. It is an isomer of methoxyamine and aminomethanol. It decomposes in an exothermic reaction (-63 kJ/mol) into methane and azanone unless stored as a hydrochloride salt.
