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.
