Description

Dimethisterone is a synthetic progestogen steroid hormone with significant pharmaceutical applications. Its primary value lies in its potent progestational activity, making it a key intermediate and active pharmaceutical ingredient (API) in the development of hormonal therapies. This compound is essential for manufacturers in the pharmaceutical industry, particularly those producing oral contraceptives, hormone replacement treatments, and other endocrine-related medications. We supply high-purity Dimethisterone CAS NO 79-64-1 to support global research, development, and commercial production needs.

Application

• Pharmaceutical API: Serves as a critical active pharmaceutical ingredient in oral contraceptive formulations.
• Hormone Replacement Therapy (HRT): Used in medications designed to manage menopausal symptoms and hormonal imbalances.
• Endocrine Disorder Treatment: A component in therapies for conditions like endometriosis and abnormal uterine bleeding.
• Veterinary Pharmaceuticals: Employed in hormonal treatments for reproductive management in animals.
• Biochemical Research: Used as a reference standard and reagent in steroid hormone research and assay development.
• Intermediate for Synthesis: Acts as a key building block for the synthesis of more complex steroid derivatives.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
