Chromic trioxide (CrO₃) is a strong oxidizing agent used primarily in chrome plating processes to provide a hard, corrosion-resistant, and shiny surface on metals. It serves as an key component in various industrial cleaning solutions, metal treatment baths, and the production of other chromium compounds. In organic synthesis, it is employed for the oxidation of alcohols to aldehydes or ketones, such as in the Jones oxidation. It is also utilized in catalysis for chemical reactions, the tanning of leather to enhance durability and resistance to microbial attack, and the manufacturing of dyes, pigments, and wood preservatives. Due to its hazardous nature, including high toxicity and carcinogenicity, it requires strict handling and safety protocols.
