Cr(III), or chromium in its +3 oxidation state, is a chemical compound that plays a significant role in various biological and industrial processes. It is an essential trace element for humans, contributing to glucose metabolism and insulin function. Cr(III) is commonly found in dietary sources such as meat, whole grains, and fruits. In industry, Cr(III) is used in the production of pigments, leather tanning, and as a dietary supplement. Unlike its +6 oxidation state, which is toxic and carcinogenic, Cr(III) is considered safer and is often utilized in applications that require a lower environmental impact.
