4-CHLORO-1-NAPHTHOL Usage And Synthesis
Chemical PropertiesOff white to tan crystals
Uses4-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.
UsesSuitable for visualizing protein-peroxidase conjugates in western blotting.
Synthesis Reference(s)Tetrahedron, 38, p. 2347, 1982 DOI: 10.1016/0040-4020(82)87012-9
General Description4-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 Actions4-Chloro-1-naphthol serves as a substrate for horseradish peroxidase.
Purification MethodsCrystallise the naphthol from EtOH or CHCl3. [Beilstein 6 H 611, 6 II 582, 6 III 2933, 6 IV 4233.]
