What is Stereochemistry?

The branch of chemistry concerned with the three-dimensional arrangement of atoms in molecules and how this affects chemical reactions. Stereochemistry includes the study of stereoisomers (enantiomers, diastereomers, geometric isomers) and stereochemical outcomes of reactions.

Properties & Characteristics

Stereochemistry is the study of the three-dimensional arrangement of atoms in molecules and the effects of this arrangement on physical, chemical, and biological properties. Stereoisomers have the same connectivity but differ in spatial arrangement. Main types include enantiomers (mirror images) and diastereomers. Chirality, cis-trans isomerism, and conformational analysis are key topics in stereochemistry.

Uses & Applications

Stereochemistry is critical in pharmaceutical science because enantiomers can have dramatically different biological activities. Asymmetric synthesis produces single enantiomers of drugs for greater efficacy and fewer side effects. Stereochemical knowledge is essential for understanding enzyme and receptor specificity.

Safety Information

Enantiomers can differ dramatically in toxicity (e.g., thalidomide). The stereochemistry of a drug substance is a critical quality attribute requiring verification in pharmaceutical quality control.
