Chromium sulfate is widely used in the textile industry as a mordant in dyeing processes. It helps fix dyes to fabrics, ensuring vibrant and long-lasting colors. In leather tanning, it is employed to stabilize collagen fibers, resulting in durable and flexible leather products. Additionally, it serves as a catalyst in various chemical reactions, particularly in organic synthesis. Chromium sulfate is also utilized in the production of other chromium compounds and as a component in certain wood preservatives to protect against decay and insect damage.
