Hydroxylamine sulfate

Hydroxylamine sulfate (CAS 10039-54-0), also known as hydroxylammonium sulfate or HAS, is a stable, solid salt form of hydroxylamine.

Where is Hydroxylamine sulfate used?

• Chemical synthesis: reducing agent, chemical intermediate and antioxidant stabilizer
• Personal care and cosmetics: pH adjuster and antioxidant stabilizer in hair color and skin-lightening products
• Agricultural chemicals: key intermediate in the production of oximes, precursors to herbicides and pesticides
• Textile and leather processing: fiber treatment and reducing agent in dye stripping and surface preparation
• Pharmaceutical manufacturers employ HAS in the synthesis of active intermediates, particularly in oxime-based reaction pathways.

Good to know: Moisture-controlled packaging is required to maintain product stability during storage and transit.

Commercial specifications

• Technical grade for industrial synthesis; higher-purity grades for pharmaceutical and cosmetic manufacturing
• Packaging from small drums to bulk quantities
