Description

(25Rs)-Ruscogenin CAS NO 874485-32-2 is a high-purity, specific stereoisomer of the natural steroidal sapogenin, ruscogenin. This compound is of significant interest for its role as a critical reference standard and a key intermediate in pharmaceutical research and development. It is primarily sought after by manufacturers and research institutions in the pharmaceutical, nutraceutical, and fine chemical sectors for developing and standardizing therapeutic agents.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the quality control and assay of ruscogenin-containing drugs and herbal extracts.
• Active Pharmaceutical Ingredient (API) Intermediate: Serves as a crucial chiral building block in the synthesis of novel steroidal drugs targeting inflammation and vascular conditions.
• Nutraceutical Research: Employed in the development and standardization of high-value dietary supplements aimed at supporting vascular health.
• Biochemical Research: Utilized in pharmacological studies to investigate structure-activity relationships (SAR) and metabolic pathways of steroidal sapogenins.
• Analytical Chemistry: Acts as a high-purity calibration standard in chromatographic (HPLC, GC) and spectroscopic analyses.

Quality Control

Our (25Rs)-Ruscogenin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for stereoisomeric confirmation, and identity verification via IR and NMR spectroscopy. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or cGMP 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 in a dry environment and away from direct light exposure to maintain stability and purity.
