Used as a reducing agent in organic synthesis, particularly in the production of oximes from ketones or aldehydes. Commonly applied in analytical chemistry for the determination of carbonyl compounds. Serves as a precursor in the synthesis of caprolactam, a key intermediate for nylon-6. Also utilized in electroless plating processes to stabilize baths and improve deposit quality. Finds use in photographic developing solutions and as a scavenger for aldehydes in industrial systems.
