Description

3β-Hydroxy-21-Oxoolean-12-En-28-Oic Acid CAS NO 511-81-9 is a pentacyclic triterpenoid compound of significant interest in pharmaceutical and biochemical research. This compound serves as a crucial intermediate and reference standard in the development of novel therapeutic agents, particularly due to its structural relationship to bioactive oleanane-type triterpenes. It is primarily sought by research institutions, pharmaceutical development laboratories, and manufacturers of high-purity biochemicals for applications in drug discovery and analytical chemistry.

Application

• Pharmaceutical Intermediate: Serves as a key synthetic precursor for the development of novel anti-inflammatory, hepatoprotective, and anti-cancer agents.
• Biochemical Research: Used as a reference standard and analytical marker in the study of triterpenoid metabolism, biosynthesis, and biological activity.
• Natural Product Isolation & Standardization: Employed as a certified reference material (CRM) for the qualitative and quantitative analysis of plant extracts containing oleanane-type triterpenes.
• Academic Research: Utilized in university and institutional labs for structure-activity relationship (SAR) studies and pharmacological screening.
• Cosmeceutical Development: Investigated as a potential active ingredient in advanced skincare formulations targeting inflammation and oxidative stress.
• Quality Control & Assurance: Acts as a high-purity standard for the calibration of analytical equipment (HPLC, LC-MS) in quality control laboratories.
