Description

3β-Acetyloxyolean-12-En-28-Oic Acid Methyl Ester is a high-purity, semi-synthetic derivative of oleanolic acid, a pentacyclic triterpenoid of significant commercial and research interest. This compound serves as a critical intermediate in the synthesis of novel bioactive molecules, offering a versatile scaffold for pharmaceutical and nutraceutical development. It is primarily sought by research institutions, pharmaceutical R&D departments, and fine chemical manufacturers engaged in developing anti-inflammatory, hepatoprotective, and metabolic disorder therapeutics.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of novel triterpenoid-based drug candidates targeting inflammation, cancer, and liver diseases.
• Biochemical Research: Used as a reference standard and probe in pharmacological studies to investigate structure-activity relationships (SAR) of oleanane-type triterpenes.
• Nutraceutical Development: Serves as a precursor for the development of enhanced bioavailability forms of oleanolic acid for dietary supplements.
• Cosmetic Ingredient Synthesis: Intermediate in creating specialized active ingredients for anti-aging and skin-soothing cosmetic formulations.
• Academic Research: Utilized in university and institutional labs for organic synthesis projects and natural product chemistry studies.
• Process Development: Employed in scale-up and optimization studies for the industrial production of triterpenoid derivatives.
