Description and Uses
4-hydroxybenzenesulfonic acid is an arenesulfonic acid that is phenol substituted by a sulfo group at C-4. It is functionally related to a phenol. Results obtained in a comparative study using the disulfide-bridge containing peptide deaminoarginine-vasopressin and several commonly used matrices indicate that the reduction-inhibiting efficiency of 4-hydroxy benzene sulfonic acid is comparable to that of 3-nitrobenzyl alcohol while reduction is found to be important in matrices such as thioglycerol and glycerol. Experiments conducted on peptides such as met-enkephalin and bradykinin, nucleosides and other polar compounds reveal that 4-hydroxybenzenesulfonic acid is a good solvent and has physical properties similar to glycerol. This new matrix material is a radical scavenger, is surface active, allows persistent secondary-ion beams, and produces a low background signal[1].
4-Hydroxybenzenesulfonic Acid is used as a redox-mediator in the laccase-catalyzed degradation of indigo, a textile dye. Also used in oilfield chemicals, metal working, and as a polymerization catalyst.
