Description

20β-Dihydrodydrogesterone is a synthetic progestogen, a key pharmaceutical intermediate and active pharmaceutical ingredient (API). This compound is valued for its high purity and stability, making it essential for the development and production of advanced hormonal therapies. It is primarily required by pharmaceutical manufacturers and research institutions focused on endocrinology, women's health, and steroid chemistry.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of advanced progestogen-based active pharmaceutical ingredients (APIs).
• Hormone Replacement Therapy (HRT): Used in the research and development of formulations for managing menopausal symptoms and hormonal imbalances.
• Gynecological Therapeutics: Serves as a key component in the production of medications for menstrual disorders and endometriosis.
• Steroid Research: An important reference standard and starting material in academic and industrial steroid chemistry research.
• API Manufacturing: Employed in cGMP-compliant processes for the commercial-scale production of finished dosage forms.
• Veterinary Pharmaceuticals: Used in developing hormonal treatments for animal health applications.

Quality Control

Our 20β-Dihydrodydrogesterone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for assay and related substances, to ensure it meets high-purity standards suitable for pharmaceutical use. Certificates of Analysis (COA) are provided, confirming compliance with relevant specifications. We support development with custom purity grades and can align with pharmacopeial standards (e.g., EP, USP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed to minimize exposure to atmospheric moisture and light to maintain stability and purity.
