Pyrrole-2-carboxylic acid is an organic compound with the formula HNC₄H₃CO₂H. It is one of two monocarboxylic acids of pyrrole. It is a white solid. It arises in nature by dehydrogenation of the amino acid proline.^[1] It also arises by carboxylation of pyrrole.^[2] The ethyl ester of this acid is readily prepared from pyrrole.^[3]
