Molecular Formula : C21H28O2
Formula Weight : 312.45
Description :
Norgestrel is a progestin used in hormonal contraceptives. Norgestrel is a mixture of two stereoisomers, dextro-norgestrel (CAS# 797-64-8) and levo-norgestrel (CAS# 797-63-7). Only levonorgestrel is biologically active. Therefore, while some medications may contain dextronorgestrel, they are often labeled in terms of their levonorgestrel content only, ignoring the inert isomer.
