Dextronorgestrel

Dextronorgestrel is the inactive isomer of norgestrel with no significant progestational activity. It is mainly relevant in chiral purity analysis, impurity profiling, and stereoisomeric separation studies to ensure that levonorgestrel drug substances contain only the active (S)-enantiomer for efficacy and regulatory compliance.
