Naphthol AS acetate is a fluorogenic substrate for unspecified esterases. After cleavage of the fluorigenic substrate by esterases the free Naphthol AS can couple with diazonium salts to form different types of fluorescent azo dyes. Human and bovine serum albumin are active against Naphthol AS acetate, resulting in a fluorescence excited at 320nm and monitored at 500nm. Can also be used as a bulding block or intermediate for organic synthesis.
