Naphthol AS-TR phosphate disodium

Naphthol AS-TR Phosphate disodium, a water-soluble dye, serves as an enzymatic substrate in biochemical assays to measure alkaline phosphatase activity. Its unique chemical properties enable hydrolysis by alkaline phosphatase, resulting in a colored product detectable spectrophotometrically. This characteristic renders it valuable for assessing enzyme activity in biological samples, including serum and urine.
