Description

Chlormadinon is a synthetic progestogen steroid hormone, widely recognized for its potent biological activity. This compound is a critical intermediate and active pharmaceutical ingredient (API) in the development and manufacturing of hormonal therapeutics. It is essential for pharmaceutical companies and research institutions focused on endocrinology and reproductive health. The product is supplied under the identifier CAS NO 1961-77-9, ensuring precise identification and traceability.

Application

• Pharmaceutical API: Primary use as an active pharmaceutical ingredient in hormonal medications, particularly progestogen-based therapies.
• Hormone Replacement Therapy (HRT): A key component in formulations designed to treat menopausal symptoms and hormonal imbalances.
• Contraceptive Formulations: Used in the synthesis of certain oral contraceptives and other birth control products.
• Gynecological Treatments: Employed in medications for managing conditions like endometriosis, dysmenorrhea, and abnormal uterine bleeding.
• Veterinary Pharmaceuticals: Applied in hormonal treatments for animal health and reproduction management.
• Biochemical Research: Serves as a reference standard and reagent in steroid hormone research and assay development.
• Chemical Synthesis: Acts as a crucial intermediate for the synthesis of more complex steroid derivatives and novel drug candidates.

Quality Control

Our Chlormadinon is manufactured under strict quality management systems to ensure it meets the high standards required for pharmaceutical applications. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling via HPLC and other validated methods. We provide full traceability and Certificates of Analysis (COA) are available for every shipment, confirming compliance with relevant specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, open flames, and incompatible materials. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
