Description

General description

4-Formylbenzoic acid is an important intermediate in the synthesis of terepthalic acid. It reacts with barium carbonate to yield two-dimensional barium(II) coordination polymer.

Application

4-Formylbenzoic acid has been used as reagent during esterification of 2,2,6,6-tetramethyl-4-oxopiperidinyl-1-oxyl to yield 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl 4-formylbenzoate.

It can also be used as a reagent to synthesize acid functionalized mesoporous silica catalyst by the condensation of its aldehyde group with -NH₂ of amine functionalized silica.
