Description

Ulipristal Acetate 17-Belta Isomer is a specific stereoisomer of the selective progesterone receptor modulator (SPRM) ulipristal acetate. This high-purity intermediate is critical for the research and development of targeted therapeutic agents, particularly in the field of reproductive health and gynecological medicine. It is primarily utilized by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the synthesis of advanced active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of the active pharmaceutical ingredient Ulipristal Acetate.
• Research & Development: Used in preclinical and clinical studies to investigate the efficacy and safety profile of SPRM-based therapies.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in pharmaceutical analysis.
• Process Chemistry: Employed in route scouting and optimization for the scalable manufacturing of Ulipristal Acetate API.
• Academic Research: Utilized in university and institutional labs for studying progesterone receptor biology and signaling pathways.

Quality Control

Our Ulipristal Acetate 17-Belta Isomer is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral purity, to ensure it meets the stringent requirements for pharmaceutical research and development. A Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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.
