Description

18-Methyl Mestranol is a synthetic steroidal estrogen, a derivative of ethinyl estradiol. This high-purity intermediate is critical for ensuring the quality and efficacy of final pharmaceutical formulations. It is primarily utilized by manufacturers in the pharmaceutical industry for the synthesis of advanced hormonal therapies and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of steroidal drugs and hormonal medications.
• Active Pharmaceutical Ingredient (API) Production: Used in the manufacture of specific estrogen-based APIs for therapeutic applications.
• Research & Development: Serves as a critical reference standard and starting material in pharmaceutical R&D for novel hormone therapies.
• Contraceptive Formulations: Employed in the development and production of certain hormonal contraceptive agents.
• Veterinary Pharmaceuticals: Used in the synthesis of hormonal treatments for veterinary medicine.
