Overview
17α-Hydroxyprogesterone (17α-OHP) is a naturally occurring progestogen and a critical intermediate in steroid hormone biosynthesis. It serves as a precursor in the production of glucocorticoids, mineralocorticoids, and androgens in both adrenal glands and gonads. Industrially, it is synthesized for pharmaceutical applications, particularly as a starting material for anti-inflammatory drugs and hormonal therapies. The compound gained significance after its role in congenital adrenal hyperplasia (CAH) was discovered. Today, pharmaceutical-grade 17α-OHP is manufactured under strict quality controls for use in steroid synthesis and medical research.
Physical and Chemical Properties
As a steroid compound, 17α-hydroxyprogesterone exhibits typical characteristics of hydrophobic molecules. Its crystalline form shows stability at room temperature when protected from light and moisture. The molecule contains ketone and hydroxyl functional groups that participate in various biochemical transformations. The substance's poor water solubility necessitates organic solvents for laboratory or industrial use. Its melting point around 220°C indicates thermal stability during processing. Spectroscopic properties include characteristic UV absorption at 240 nm, useful for analytical quantification.
Main Applications
In pharmaceutical manufacturing, 17α-OHP serves as the key intermediate for synthesizing cortisol, cortisone, and other corticosteroids through microbial or chemical transformations. It's also used to produce testosterone derivatives and certain progestins. These end-products treat conditions ranging from inflammation to hormonal disorders. The compound has diagnostic applications in clinical biochemistry for assessing adrenal function. Research laboratories utilize 17α-OHP to study steroidogenesis pathways and develop new enzymatic conversion methods for more efficient drug production.
Safety and Storage
While not classified as acutely toxic, 17α-hydroxyprogesterone requires careful handling due to potential hormonal activity. Powder handling should occur in controlled environments with appropriate personal protective equipment (PPE) including gloves and safety glasses to prevent skin contact or inhalation. Proper storage involves airtight containers with desiccants, maintained at stable temperatures below 25°C. Prolonged exposure to heat, light, or humidity may degrade the compound. Facilities should follow pharmaceutical storage guidelines and monitor inventory for stability over time.
B2B Procurement Guide
Pharmaceutical buyers should prioritize suppliers with documented GMP compliance and consistent batch-to-batch quality. Key specifications include HPLC purity (typically ≥98%), residual solvent levels, and microbiological limits. Certificates of Analysis (CoA) should accompany each shipment. For bulk procurement, consider suppliers offering stability data and regulatory support documentation. Pricing varies significantly based on quantity (grams to kilograms), purity grade, and packaging requirements. Long-term contracts with quality-approved vendors often provide better consistency than spot purchases.
