Phenylacetylcarbinol (PAC) is an organic compound that has two enantiomers, one with R- and one with S-configuration. (R)-PAC, which is commonly called L-PAC, is known as a precursor in the synthesis of pharmaceuticals such as ephedrine and pseudoephedrine.
(R)-PAC or (R)-(−)-phenylacetylcarbinol is identical to l-PAC, referring to the outdated d/l system. (R)-PAC is the levo-rotating isomer of phenylacetylcarbinol.

(R)-PAC or (R)-(−)-phenylacetylcarbinol is identical to l-PAC, referring to the outdated d/l system. (R)-PAC is the levo-rotating isomer of phenylacetylcarbinol.
The IUPAC name of phenylacetylcarbinol is 1-hydroxy-1-phenylpropan-2-one. Synonyms are 1-hydroxy-1-phenyl-2-propanone and 1-Hydroxy-1-phenylacetone.
L-PAC is widely synthesized by fermentation of benzaldehyde and dextrose. In this process, colonies of yeast (in particular, strains such as Candida utilis, Torulaspora delbrueckii, or Saccharomyces cerevisiae) are cultivated and added to a broth of water, dextrose, and the enzyme pyruvate decarboxylase in a vat. The yeast is left to grow for a period of time, after which the benzaldehyde is introduced into the broth. The...
