Biological Activity: Leucocrystal violet is a cationic triarylmethane dye. Leucocrystal violet generates a colored purple product in the presence of hydrogen peroxide and horseradish peroxidase, or when oxidized by periodate under the catalysis of horseradish peroxidase. Leucocrystal violet serves as a chromogenic reagent for the determination of submicrogram-level hydrogen peroxide, with no interference from tryptophan, persulfate or chromate. Leucocrystal violet reacts with blood to produce a purple/violet color in the presence of hydrogen peroxide; it forms a very weak fluorophore when acting with whole blood in an unbuffered solution, with a maximum absorption wavelength of 630 nm and a maximum fluorescence emission wavelength of 665 nm upon excitation at 630 nm. Leucocrystal violet is widely used for staining blood residues on porous and non-porous materials[1][2].
