Description

3β,17-Hydroxypregn-5-En-20-One Monoacetate is a high-purity steroid derivative, also known as 17-Hydroxypregnenolone Acetate. This compound serves as a critical pharmaceutical intermediate and a valuable reference standard in research and development. It is primarily required by manufacturers and research institutions in the pharmaceutical, biotechnology, and fine chemical sectors for the synthesis of more complex steroid hormones and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of steroidal drugs, including corticosteroids and other hormone-based therapies.
• Reference Standard: Used as a certified reference material (CRM) in analytical laboratories for method development, validation, and quality control testing of related steroid products.
• Biochemical Research: Employed in metabolic pathway studies and enzymatic research related to steroidogenesis and hormone biosynthesis.
• Fine Chemical Synthesis: Utilized as a starting material or intermediate for the preparation of novel steroid analogs with potential biological activity.
• Academic & Contract Research: Serves as a reagent in university and CRO (Contract Research Organization) settings for investigative studies in endocrinology and medicinal chemistry.

Quality Control

Our 3β,17-Hydroxypregn-5-En-20-One Monoacetate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and specific tests for residual solvents and related substances. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and in original packaging until use to prevent degradation.
