Ethyl Violet
Ethyl Violet (CAS: 2390-59-2; Formula: C31H42N3Cl; Molar Mass: 492.14 g/mol) is a cationic triarylmethane dye and the ethyl homolog of crystal violet. It functions as a versatile histological and pathological stain. This dye has found application in staining pancreatic tissue and elastin, identifying Gram-negative bacteria, and in extractive-spectrophotometric analysis of anionic surfactants and copper. It is also used in SDS-polyacrylamide gel electrophoresis for protein counterstaining.
