Off white to tan crystals | [Uses]
4-Chloro-1-naphthol has been used to visualize protein bands in western blotting. It has also been used in staining polyvinylidene fluoride (PVDF) membrane by Nakane method. | [Synthesis Reference(s)]
Tetrahedron, 38, p. 2347, 1982 DOI: 10.1016/0040-4020(82)87012-9 | [General Description]
4-Chloro-1-naphthol is primarily used for the detection of proteins, it gives a characteristic purple precipitate and the reactions are easily controllable. It can be used as a substitute for benzidine compounds, which are considered to be carcinogenic. | [Biochem/physiol Actions]
4-Chloro-1-naphthol serves as a substrate for horseradish peroxidase. | [Purification Methods]
Crystallise the naphthol from EtOH or CHCl3. [Beilstein 6 H 611, 6 II 582, 6 III 2933, 6 IV 4233.] |
