CAS 76-03-9: Trichloroacetic acid

Description:Trichloroacetic acid (TCA) is a colorless, odorless, and highly corrosive organic compound with the chemical formula CCl3COOH. It is a derivative of acetic acid, where three hydrogen atoms are replaced by chlorine atoms. TCA is a strong acid, exhibiting a pKa value that indicates its ability to dissociate in aqueous solutions, making it a potent acid in various chemical reactions. It is soluble in water, alcohol, and ether, which enhances its utility in laboratory and industrial applications. TCA is commonly used as a reagent in organic synthesis, particularly in the preparation of carboxylic acids and as a catalyst in certain reactions. Additionally, it has applications in the medical field, notably in dermatology for chemical peels and wart removal due to its ability to denature proteins. However, due to its corrosive nature, it poses health risks, necessitating careful handling and appropriate safety measures to prevent skin and respiratory irritation.
