Phenibut Stereochemistry & Enantiomers
Phenibut contains a single stereocenter, so it exists as two mirror-image forms. This page describes that stereochemistry as structural chemistry.
The stereocenter
The carbon bearing the phenyl group (C-3 of the butanoic acid chain) is a stereocenter. As a result Phenibut can exist as the R-enantiomer and the S-enantiomer, and as the racemate (an equal mixture of both).
Racemic vs. single-enantiomer material
Material supplied as a research chemical is typically racemic unless documentation specifies a single enantiomer. The individual enantiomers have been prepared and studied separately in the chemical literature. Enantiomeric composition, where determined for a lot, would appear on the applicable documentation.
Why it matters for documentation
Stereochemistry can be relevant to analytical characterization and reproducibility. See analytical identification and the chemical reference.
