Hydroxyl Amine Sulfate (CAS 10039-54-0) is a high-purity inorganic salt that appears as white crystals or powder, is highly soluble in water and slightly hygroscopic, and serves as a reducing agent and chemical intermediate that converts aldehydes and ketones into oximes and provides a stable source of hydroxylamine. In the pharmaceutical sector, it is a critical synthetic intermediate for the production of various medicines and agrochemicals. It is valued for its ability to convert aldehydes and ketones into oximes with high efficiency. This specialty chemical also functions as an effective oxygen scavenger in high-pressure boiler water systems. It is preferred in industrial processes where a stable source of hydroxylamine is required for delicate reactions.
