Norgestrel is an old progestin that has been 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.
