BCIP, Toluidine

BCIP, toluidine (5-Bromo-4-chloro-3-indoxyl phosphate, p-toluidine salt) is a widely used chromogenic phosphatase substrate, which forms a dark blue (lambdamax 615 nm) precipitate on enzymatic hydrolysis. It is often used with the oxidant NBT (nitro blue tetrazolium chloride), which facilitates the precipitation.Store at 4°C and protect from lightC15H15BrClN2O4PMW: 433.6[6578-06-9]
