Detection and determination of the hydrazo and azo photoproducts of 4-aminobenzoic acid by high-performance liquid chromatography.

Abstract:

:The photochemistry of 4-aminobenzoic acid has been investigated using two validated reversed-phase HPLC methods. Up to nine photoproducts have been detected, with chromatographic evidence for the formation of 4,4'-azobenzenedicarboxylic acid and 4,4'-hydrazobenzenedicarboxylic acid. The synthesis and analytical characterization of 4,4'-hydrazobenzenedicarboxylic acid is reported.
