CAS 1333-82-0

Chromium trioxide

Description:

Chromium trioxide, with the CAS number 1333-82-0, is a highly toxic and corrosive chemical compound that appears as a dark red to black solid or crystalline powder. It is primarily known for its strong oxidizing properties, making it useful in various applications, including metal finishing, electroplating, and as a reagent in organic synthesis. Chromium trioxide is hygroscopic, meaning it readily absorbs moisture from the air, and it can dissolve in water to form a highly acidic solution. This compound is classified as a carcinogen and poses significant health risks, including respiratory issues and skin irritation upon exposure. Due to its hazardous nature, chromium trioxide is subject to strict regulations regarding its handling, storage, and disposal. In addition to its industrial uses, it plays a role in the production of chromium salts and as a catalyst in certain chemical reactions. Proper safety measures, including personal protective equipment and adequate ventilation, are essential when working with this substance to mitigate its toxic effects.
