Basic green 4

Basic green 4 (Malachite green) is a cationic dye that is widely used as a bactericide in aquaculture and is also commonly used in laboratories for the determination of phosphates. Basic green 4 exhibits high cytotoxicity and carcinogenicity to mammalian cells, specifically shown by its IC50 values of 2.03 µM for HEp-2 human laryngeal cells and 13.8 µM for Caco-2 human colorectal adenocarcinoma cells, and it can promote the development of liver tumors. The maximum absorbance wavelength is 621 nm[1][2][3].
