Definition
ChEBI: An oxo carboxylic acid that is pyruvic acid in which one of the methyl hydrogens is substituted by a 4-hydroxyphenyl group.
General Description
4-hydroxyphenylpyruvic acid can be determined in pork meat and Iberian ham samples by a sensitive method of multiple reaction monitoring (MRM) by mass spectrometry.
Purification Methods
p-Hydroxyphenylpyruvic acid [156-39-8] M 180.2, m 220o(dec), pKEst ~2.3. Crystallise it three times from 0.1M HCl/EtOH (4:1, v/v) immediately before use [Rose & Powell Biochem J 87 541 1963], or from Et2O. The 3,4-dinitrophenylhydrazone has m 178o. [Beilstein 10 IV 3630.]
