Used as a corrosion inhibitor in cooling water systems and industrial recirculating water to protect metal surfaces, especially in heat exchangers and pipelines.

Acts as an oxidizing agent in chemical synthesis, particularly in the production of other chromium compounds, including chromate pigments for paints and coatings.

Employed in the treatment of metal surfaces to improve adhesion and durability of coatings, and in electroplating processes such as chromium and zinc plating.

Also utilized in the tanning of leather to enhance resistance to microbial degradation.

Its strong oxidizing properties make it suitable as a mordant in dyeing textiles and in analytical laboratories for the determination of reducing substances.
