Used primarily in the synthesis of oximes, which are key intermediates in the production of pesticides, pharmaceuticals, and polymer stabilizers. Serves as a reducing agent in photographic developers and in the regeneration of noble metal catalysts. Employed in the preparation of hydroxylamine-O-sulfonic acid, a versatile aminating agent for introducing amino groups into organic compounds. Plays a role in analytical chemistry for the determination of carbonyl compounds like aldehydes and ketones. Also utilized in the semiconductor industry for cleaning and surface modification of silicon wafers due to its ability to remove native oxides.
