Application

Phthalic acid may be used in the synthesis of benzoic acid. It may be used to constitute the mobile phase during hydrophilic interaction liquid chromatography (HILIC) coupled with electrospray ionization tandem mass spectrometric (ESI-MS/MS) analysis of free amino acids (AAs) in human thyroid tissues.

General description

Phthalic acid (1,2-benzenedicarboxylic acid) is an aromatic dicarboxylic acid. On heating, it undergoes dehydration to afford cyclic anhydride. It can be synthesized from phthalic anhydride.
