PRODUCT INTRODUCTION
description
2-(4-hydroxyphenylazo)benzoic acid is 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/ionization (MALDI) mass spectrometry. It has a role as a MALDI matrix material. It is a member of phenols, a monocarboxylic acid and a monoazo compound. It is functionally related to an azobenzene.
