2-(4-Hydroxyphenylazo)benzoic acid Chemical Properties,Uses,Production

Chemical Properties

light yellow to orange powder

Uses

2-(4-Hydroxyphenylazo)benzoic acid may be used in the preparation of:

  • 2-((4-(3,4-dicyanophenoxy)phenyl)diazenyl)benzoic acid
  • 2,2′-((((4,5-dicyano-1,2-phenylene)bis(oxy))bis(4,1-phenylene))bis(diazene-2,1-diyl)) dibenzoic acid
  • a multifunctional benzoxazine monomer

Definition

ChEBI: An azo compound that is azobenzene in which one phenyl group is substituted at position 4 by a hydroxy group, while the other phenyl group is substituted at position 2 by a carboxy group. It is used as a matrix in matrix-assisted laser desorption/ionizatio (MALDI) mass spectrometry.

General Description

2-(4-Hydroxyphenylazo)benzoic acid) (HABA), can be used for desorption of proteins, peptides and glycoproteins, thereby making it very advantageous for matrix-assisted laser desorption ionization mass spectrometry.
