4-Hydroxyphenylpyruvic acid Chemical Properties,Usage,Production

Chemical Properties

grey to orange-brown powder

Uses

4-Hydroxyphenylpyruvic Acid is general organic reagent used in the synthesis of latifolicinin A analogs as inhibitors of breast cancer. Also used in the preparation of amperometric biosensors for β-triketone herbicides based on hydroxyphenylpyruvate.

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.]
