Beschreibung

Anwendung

4-(4′-Hydroxyphenylazo)benzoic acid may be used to synthesize 4-(4-propyloxyphenylazo)benzoic acid via Williamson synthesis by reacting with 1-bromopropane.

Azobenzene cleavable linker. Treatment with sodium dithionite (sodium hydrosulfite) reduces azo functionality, cleaving the N-N bond to yield two primary amines.
Has been used in proteomic and affinity chromatography applications.
