Hazards
MSDS External MSDS
Phenylacetic acid (abr. PAA and synonyms are: α-toluic acid,
benzeneacetic acid, alpha tolylic acid, 2-phenylacetic acid) is an
organic compound containing a phenyl functional group and an acetic
acid functional group.
Because it is used in the illicit production of phenylacetone (used
in the manufacture of meth/amphetamines), it is subject to controls
in the United States.

Applications
Phenylacetic acid is used in some perfumes, possessing a
honey-like odour in low concentrations, and is also used in
penicillin G production. It is also employed to treat type II
hyperammonemia to help reduce the amounts of ammonia in a
patient's bloodstream by forming phenylacetyl-CoA which then
reacts with nitrogen-rich glutamine to form
phenylacetylglutamine. This compound is then secreted by the
patient's body.
Phenylacetic acid is a white crystals with a disagreeable odor;
boiling point 262 C; soluble in alcohol and ether. It serves as
an ingredient in perfume to provide honey-like odor. It is found
as a moiety in some alkaloids and plant hormones. It is formed
as catabolite of phenylalanine. In toluic acid name system,
phenylacetic acid is alpha-toluic acid which one of the hydrogen
atoms in the methyl group has been substituted instead of the
substitution in the benzene ring.
Substituted phenylacetic acid molecule at alpha position and
phenylacetate esters can serve as a drug with a wide variety of
effects including anticholinergic, muscarinic antagonist,
antidote to cholinesterase inhibitors or toxins, cycloplegic and
mydriatic. Phenylacetic acid is used to prepare a nonsteroidal
antiinflammatory drug like diclofenac. It is used the
manufacture of penicillin. Mandelic Acid, phenylglycollic acid,
can be produced from phenylchloracetic acid.
