Used as a reducing agent in chemical synthesis, particularly in the production of oximes from ketones and aldehydes, such as the conversion of cyclohexanone to cyclohexanone oxime, a key precursor in nylon-6 production. Commonly applied in analytical chemistry for the determination of carbonyl compounds and for detecting or separating metals like manganese and iron through specific complex formation. Also serves in the preparation of hydroxylamine-O-sulfonic acid, a reagent in organic synthesis. Employed in photography as a component in developers, in textile industries for bleaching and finishing processes, and in surface coating applications. Additionally, used in the synthesis of certain pharmaceuticals, agrochemicals, and pesticide formulations where selective reduction, as a precursor, or catalyst is required.
