General description

Methoxyamine hydrochloride is a commonly used reagent for the generation of oxime derivatives of aldehyde- or ketone-group containing compounds. It is typically employed as an oximation reagent prior to silylation derivatizations.

Application

Methoxyamine hydrochloride can be used as:
  • A reagent for the preparation of O-methyl oximes.
  • A reagent used to make O-methyl oximes from aldehydes or ketones.
  • An alkylation reagent.
  • It may be used as a derivatization agent to improve the sensitivity of opioids, steroids and ionic metabolites in biological samples and non-volatile flavor compounds in "Angeleno" plum fruit prior to the determination of analytes using gas chromatography-mass spectrometry (GC-MS) technique.
