Descriptions:
pubchem: 2,4-dihydroxybenzoic acid is a dihydroxybenzoic acid that is benzoic acid substituted by hydroxy groups at positions 2 and 4. It has a role as a flavouring agent, a plant metabolite and a human urinary metabolite. It is a dihydroxybenzoic acid, a monocarboxylic acid and a member of resorcinols. It is a conjugate acid of a 2,4-dihydroxybenzoate.
chebi: A dihydroxybenzoic acid that is benzoic acid substituted by hydroxy groups at positions 2 and 4.
wikipedia: 2,4-Dihydroxybenzoic acid (β-resorcylic acid) is a dihydroxybenzoic acid.
As a resorcylic acid, it is one of the three isomeric crystalline acids that are both carboxyl derivatives of resorcinol and dihydroxy derivatives of benzoic acid. Synthesis from resorcinol is via the Kolbe-Schmitt reaction.  
It is a degradation product of cyanidin glycosides from tart cherries in cell cultures. It is also a metabolite found in human plasma after cranberry juice consumption.
