Used as a reducing agent in chemical synthesis and electroplating processes, particularly in tin plating of metals to prevent corrosion, such as in the electronics industry for plating printed circuit boards or electrical connectors. Employed in the preparation of other tin compounds and in textile dyeing as a mordant to fix colors. Also utilized in some analytical chemistry procedures for the detection and estimation of certain anions. Its reducing properties make it suitable in organic transformations where controlled reduction is required.
