Naphthol AS-BI is a fluorescent dye commonly used as a building block or intermediate to produce fluorigenic substrates or as a coupling reagent to produce azo dyes. After cleavage of the fluorigenic substrates by esterases the free Naphthol AS-BI can couple with diazonium salts to form different types of fluorescent azo dyes.
