Descrizione generale

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.

Applicazioni

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.

This study focuses on the disassembly-behavior of self-immolative pro-fluorescent linkers under physiological conditions and through an enzyme-initiated domino reaction. The targeted linkers are based on para-aminobenzylalcohol (PABA) or hemithioaminal derivatives of para-carboxybenzaldehyde or glyoxilic acid. We found that a fine
