Description

Hydroxylamine Sulfate is an important inorganic salt widely used as a versatile reducing agent and intermediate in chemical synthesis. Its primary value lies in its ability to selectively reduce functional groups and serve as a source of hydroxylamine, making it critical for producing high-purity compounds. This product is essential for manufacturers in the pharmaceutical, agrochemical, photographic, and polymer industries who require reliable, consistent raw materials for their processes.

Application

• Pharmaceutical Intermediate: Key starting material in the synthesis of various active pharmaceutical ingredients (APIs), including oximes and specific antibiotics.
• Photographic Industry: Used as a stabilizer and developing agent in photographic developers and emulsions.
• Polymer & Rubber Industry: Acts as a shortstop agent to terminate free-radical polymerization reactions and as an antioxidant stabilizer.
• Agrochemical Synthesis: Intermediate in the production of certain herbicides, pesticides, and plant growth regulators.
• Analytical Chemistry: Employed as a reagent for the determination of aldehydes and ketones, and in titrimetric analysis.
• Metal Surface Treatment: Used in metal plating and finishing processes as a reducing agent and corrosion inhibitor.
• Dye & Pigment Manufacturing: Serves as a reducing agent in the synthesis of specific dyes and organic pigments.
• Research & Development: Utilized in laboratory-scale organic synthesis and as a reagent in various chemical research applications.

Quality Control

Our Hydroxylamine Sulfate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profiles, and physical characteristics. Our quality commitment ensures reliable consistency and suitability for demanding industrial and fine chemical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. As the compound is easily oxidized, storage under an inert atmosphere (e.g., nitrogen) is recommended for long-term stability of opened containers. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases.
