4-Hydroxyphthalic acid Usage And Synthesis

Chemical Properties	off-white to white powder
Uses	4-Hydroxyphthalic acid is used as a precursor to prepare 3,5-dichloro-4-hydroxyphthalic acid using the reagent aqueous acetic acid and chlorine. Further, it is also used as a starting material in the manufacture of N-(4-carboxyphenyl)-4-acetoxyphthalimide.
Definition	ChEBI: 4-hydroxyphthalic acid is a hydroxybenzoic acid that is phthalic acid in which the hydrogen at position 4 is substituted by a hydroxy group. It is a member of phenols and a hydroxybenzoic acid. It derives from a phthalic acid.
