Chromium Fluoride (CAS 7788-97-8) is a green crystalline chromium(III) salt, typically in trihydrate form, that serves as a mordant in industrial dyeing for wool and silk and as a metal-finishing and plating agent in automotive production. It is essential in industrial dyeing to ensure superior color fastness on wool and silk fibers.

In the automotive sector, it is used in metal finishing and plating to provide a durable, corrosion-resistant surface. Its purity is vital for maintaining the stability of electroplating baths and preventing surface defects.

The compound also functions as a catalyst in organic chemistry, particularly in halogen exchange reactions. This green crystalline solid is valued for its consistent chemical reactivity in demanding industrial environments.
