  • Applications

    Hydroxylamine sulfate (CAS 10039-54-0) is primarily used as a source of hydroxylamine for organic synthesis, notably in oxime formation from carbonyl compounds under appropriate conditions; it is also employed as a reducing agent in various syntheses to convert nitro groups to amines or to participate in pharmaceutical and pigment-related reaction sequences; it serves as an important chemical intermediate in the production of dyes and pigments for textile and printing applications; it can be used in pharmaceutical manufacturing as an intermediate for APIs; and it may function as an analytical reagent to form oxime derivatives for structural confirmation of carbonyl compounds. Subject to local regulations and formulation limits.
