Description

Ulipristal Acetate is a selective progesterone receptor modulator (SPRM) of significant pharmaceutical importance. Its primary commercial value lies in its application as the active pharmaceutical ingredient (API) in emergency contraception and for the treatment of uterine fibroids. This high-purity compound is essential for manufacturers in the global pharmaceutical industry engaged in the production of finished dosage forms, clinical research, and advanced therapeutic development.

Application

• Pharmaceutical API: Primary use as the active ingredient in emergency contraceptive pills (e.g., Ella®).
• Women's Health Therapeutics: Treatment and management of moderate to severe symptoms of uterine fibroids (leiomyomas).
• Clinical Research: Utilization in preclinical and clinical studies for new drug development and formulation science.
• Reference Standard: Serves as a high-purity chemical reference standard for quality control and analytical testing in laboratories.
• Drug Formulation Development: Used in R&D for developing novel drug delivery systems and dosage forms.

Quality Control

Our Ulipristal Acetate is manufactured under strict quality management systems, targeting specifications suitable for pharmaceutical applications. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling via advanced techniques like HPLC. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure full traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider conditions under an inert atmosphere.
