Description

17β-Dihydro Equilenin 3-Sulfate Sodium Salt is a high-purity steroid sulfate derivative of significant interest in advanced pharmaceutical research and development. This compound serves as a crucial reference standard and synthetic intermediate for the production and analytical validation of steroidal pharmaceuticals. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and manufacturers of active pharmaceutical ingredients (APIs) working on hormone-related therapies and diagnostic assays.

Application

• Pharmaceutical Reference Standard: Used for the calibration of analytical equipment (HPLC, LC-MS) and method validation in quality control laboratories.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a key building block in the multi-step synthesis of complex steroidal drugs.
• Biochemical Research: Employed in studies investigating steroid metabolism, enzyme activity (sulfatases), and receptor binding assays.
• Diagnostic Development: Utilized as a critical component in the development and standardization of immunoassays and clinical diagnostic kits for hormone level detection.
• Metabolite Studies: Acts as a characterized metabolite standard in pharmacokinetic and pharmacodynamic research for drug development programs.

Quality Control

Our 17β-Dihydro Equilenin 3-Sulfate Sodium Salt is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis to ensure it meets the stringent requirements for pharmaceutical research. A Certificate of Analysis (COA) detailing all 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 should be kept in a desiccated environment to prevent moisture absorption. Keep away from incompatible materials.
