Description

2Alpha,19Alpha-Dihydroxy-3-Oxo-Urs-12-En-28-Oic Acid is a high-purity, semi-synthetic derivative of ursolic acid, a pentacyclic triterpenoid of significant research interest. This compound matters for its role as a key intermediate in the synthesis of novel bioactive molecules and for its potential in pharmacological studies targeting inflammation and metabolic pathways. It is primarily needed by pharmaceutical R&D laboratories, academic research institutions, and manufacturers of fine chemicals and reference standards for drug discovery and development programs.

Application

• Pharmaceutical Intermediate: A critical building block for the synthesis of novel triterpenoid-based drug candidates with enhanced bioavailability or targeted activity.
• Biochemical Research: Used as a reference standard or active agent in studies investigating anti-inflammatory, anti-cancer, or metabolic regulatory pathways.
• Fine Chemical Synthesis: Serves as a versatile chiral starting material for the preparation of complex natural product analogs and specialty chemicals.
• Nutraceutical Development: Explored for the formulation of advanced dietary supplements due to its structural relationship to bioactive ursane-type triterpenes.
• Academic & Contract Research: Supplied to universities and CROs (Contract Research Organizations) for fundamental chemical and biological research projects.

Quality Control

Our 2Alpha,19Alpha-Dihydroxy-3-Oxo-Urs-12-En-28-Oic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR, MS), to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or an inert atmosphere.
