olusid

Olusid is a fictional organic compound used primarily in educational settings and hypothetical discussions to illustrate key principles of stereochemistry and reaction design. The term appears in textbooks and classroom materials as an invented reference compound rather than a real chemical with established data. In typical depictions, olusid is a small, chiral molecule with at least one stereocenter, shown with simple substituents to emphasize enantiomerism. It can exist as two enantiomers, commonly labeled (R)-olusid and (S)-olusid, and may be presented in racemic form as a 50:50 mixture. Because olusid is a teaching construct, it lacks verified identifiers such as a CAS registry number, a fixed molecular formula, or published spectroscopic data in public databases.

Educational uses include illustrating how enantiomeric excess, optical rotation, and polarimetry relate to molecular structure, as well as demonstrating resolution techniques that separate enantiomers with chiral resolving agents or asymmetric synthesis concepts. In problem sets and classroom demonstrations, olusid can be combined with generic reaction schemes to discuss how stereochemical outcomes influence physical properties and reaction mechanisms. In literature and pedagogy, olusid is recognized as a hypothetical tool rather than a real-world substance, enabling clear discussion without implying factual measurements.
