General description

Crystal violet (CV) is a cationic tri-arylmethane dye, commercially used in ink and dyes. Organoclays based on CV are widely used in analytical studies.

Application

CV was used to sensitize the photooxidation of cysteine to cysteic acid, as an end product hydrogen peroxide is also formed.
