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 4C and protect from light C15H15BrClN2O4P MW: 433.6 [6578-06-9]
