  • Applications

    11a-methyl-3H,3aH,3bH,4H,5H,9bH,10H,11H-cyclopenta[a]phenanthren-7-ol is a polycyclic compound bearing a hydroxyl group at position 7 and a cyclopenta[a]phenanthren-7-ol framework. In practical terms, it can serve as a synthetic intermediate and building block for related derivatives in the pharmaceutical field; evaluated as a chiral building block for the synthesis of complex molecules; can function as a reference or calibration standard in analytical methods (e.g., LC or GC) and may be considered a specialty intermediate in industrial manufacturing to support process development for steroid-like polycyclic systems.
