Description

3,15,17-Trihydroxy-5-Androstene is a hydroxylated derivative of the androstene steroid nucleus, serving as a key intermediate in the synthesis of more complex steroid hormones and pharmaceutical agents. Its specific hydroxylation pattern at the 3, 15, and 17 positions makes it a valuable building block for research and development in medicinal chemistry. This compound is primarily utilized by pharmaceutical R&D laboratories, fine chemical manufacturers, and academic institutions focused on steroid chemistry and endocrinology.

Application

• Pharmaceutical Intermediate: A critical precursor in the multi-step synthesis of novel steroid-based therapeutics and active pharmaceutical ingredients (APIs).
• Research & Development: Used in biochemical and pharmacological research to study steroid hormone pathways, receptor interactions, and metabolic processes.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method development in steroid analysis using HPLC or LC-MS.
• Fine Chemical Synthesis: Employed as a specialized starting material for the custom synthesis of labeled compounds (e.g., deuterated or C14-labeled steroids) for tracer studies.

Quality Control

Our 3,15,17-Trihydroxy-5-Androstene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets exacting standards for research and synthesis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
