CAS No.: 121-57-3
Application: α-Naphthylamine and sulfanilic acid are used for detection of nitrate reduction by bacteria. Organisms containing nitrate reductase reduce nitrate to nitrite, which forms a diazonium salt with sulfanilic acid and reacts with α-naphthylamine to form a red azo dye.
Composition: sulfanilic acid, 8.0 g
Grade: for microbiology
Shelf Life: (limited shelf life, expiry date on the label)
