Description

20-α-Dihydrodydrogesterone is a synthetic progestogen, a key pharmaceutical intermediate and active pharmaceutical ingredient (API) derived from progesterone. This compound matters for its role in the development and production of specialized hormonal therapies and research compounds. It is primarily needed by pharmaceutical manufacturers, research institutions, and fine chemical suppliers focused on endocrinology, reproductive health, and steroid chemistry.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of advanced progestogen-based Active Pharmaceutical Ingredients (APIs).
• Hormone Research: Used as a reference standard and experimental compound in biochemical and pharmacological studies of progesterone receptor activity.
• Steroid Synthesis: Serves as a precursor in the multi-step synthesis of more complex steroidal drugs and diagnostic agents.
• Reference Standard: Employed in analytical laboratories for method development, validation, and quality control testing of related steroid products.
• Veterinary Pharmaceuticals: Potential use in the formulation of hormonal treatments for animals.

Quality Control

Our 20-α-Dihydrodydrogesterone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis to ensure it meets stringent specifications for pharmaceutical intermediates. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
