What is 3-Phenylpyruvic acid?
The Uses of 3-Phenylpyruvic acid
α-Oxobenzenepropanoic Acid is a useful reagent for organic synthesis.
Definition
ChEBI: A 2-oxo monocarboxylic acid that is 3-phenylpropanoic acid substituted by an oxo group at position 2. It is an intermediate metabolite in the phenylalanine pathway.
General Description
Phenylpyruvic acid reduces glucose-6-phosphate dehydrogenase activity without pre-incubation.
Purification Methods
Recrystallise the acid from *C6H6. The phenylhydrazone has m 173o [Zeller Helv Chim Acta 26 1614 1943, Hopkins & Chisholm Can J Research [B] 24 89 1946]. The 2,4-dinitrophenylhydrazone has m 162-164o (189o, 192-194o) [Fones J Org Chem 17 1952]. [Beilstein 10 IV 2760.]
