Used primarily in chrome plating processes to provide a protective and decorative finish on metals. It serves as a key oxidizing agent in industrial cleaning and passivation of stainless steel surfaces. Employed in the synthesis of other chromium compounds and in catalytic applications for organic reactions. Also utilized in wood preservation and as an etching agent in electronics manufacturing. Due to its strong oxidizing properties, it plays a role in laboratory-scale oxidation reactions, particularly in converting alcohols to aldehydes, ketones, or carboxylic acids.
