4-chloro-1-naphthol is a chemical compound that belongs to the group of naphthols .
properties
4-chloro-1-naphthol is used in biochemistry as a chromogenic substrate for immunostaining with a horseradish peroxidase and, after oxidation with hydrogen peroxide in the presence of dimethyl or diethyl analogues of p - phenylenediamine or o -phenylenediamine, produces via the Nadi reaction a blue dye or, in the presence of 3-methyl-2-benzothiazolinonhydrazone, a red dye, e.g. B. ELISA , Western blot and immunohistochemistry .
