3-Beta,5-Beta-Tetrahydro Levonorgestrel

3β,5β-Tetrahydro Levonorgestrel is a reduced derivative of levonorgestrel formed by hydrogenation at the 3-keto and 4,5-double bond positions. It is used in impurity profiling, stability studies, and metabolite identification. Its presence must be monitored to ensure the quality and safety of levonorgestrel drug products.
