Phenylacetylcarbinol

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. 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 (R)-PAC or (R)-(−)-phenylacetylcarbinol is identical to l-PAC, referring to the outdated d/l system.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.
