Description

3-Epiursolic Acid CAS NO 989-30-0 is a pentacyclic triterpenoid compound, a stereoisomer of the well-known ursolic acid. This compound is valued for its significant biological activity and serves as a crucial reference standard and research-grade intermediate. It is primarily sought after by research institutions and manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries for development and quality control purposes.

Application

• Pharmaceutical Research: Used as a high-purity reference standard in analytical methods (e.g., HPLC) for the quantification of ursolic acid and related triterpenoids in herbal extracts and formulations.
• Bioactivity Studies: Serves as a key intermediate or active compound in preclinical research investigating anti-inflammatory, anticancer, hepatoprotective, and metabolic regulatory properties.
• Nutraceutical Development: Incorporated into the research and development of advanced dietary supplements targeting wellness and metabolic health.
• Cosmetic & Skincare Actives: Evaluated for use in topical formulations for its potential anti-aging, skin-soothing, and antioxidant benefits.
• Chemical Synthesis: Acts as a sophisticated starting material or intermediate for the semi-synthesis of novel triterpenoid derivatives with enhanced biological profiles.
• Quality Control & Standardization: Essential for ensuring batch-to-batch consistency and potency in the production of standardized botanical extracts containing ursane-type triterpenes.
