3,4-Dihydroxybenzaldehyde, also known as protocatechuic aldehyde, is a phenolic aldehyde, a compound released from cork stoppers into wine.^[1] It is an isomer of 2,4-dihydroxybenzaldehyde.

This molecule can be used as a precursor in the vanillin synthesis by biotransformation by cell cultures of Capsicum frutescens, a type of Chili pepper.^[2] It is also found in the mushroom Phellinus linteus.^[3]

Pharmacological effects

Protocatechuic aldehyde regulates G protein-coupled estrogen receptor-1 (GPER-1) and exhibits protective effects in endothelial dysfunction and atherosclerosis.^[4]
