4-Hydroxybenzaldehyde (2-hydroxybenzaldehyde) is an organic compound with the formula C6H4OH(CHO). [4] [5] Along with 2-hydroxybenzaldehyde and 3-hydroxybenzaldehyde, it is one of the three isomers of hydroxybenzaldehyde.
4-Hydroxybenzaldehyde is prepared by reaction of phenol with chloroform, which gives isomeric hydroxy benzal chlorides. Hydrolysis of the C-Cl bonds gives the aldehyde. [5]
4-Hydroxybenzaldehyde is a precursor to 4-hydroxyphenylglycine, a precursor to penicillins. In the Dakin oxidation, 4-hydroxybenzaldehyde reacts with hydrogen peroxide in base to form hydroquinone.
p-Hydroxybenzaldehyde dehydrogenase is an enzyme found in carrots ( Daucus carota). [6]
4-Hydroxybenzaldehyde is found in the orchids Gastrodia elata, [7] Galeola faberi, [8] and the Vanilla orchids.
