Description

3β,15α,16α-Trihydroxyolean-12-En-28-Oic Acid Methyl Ester is a high-purity triterpenoid derivative, a methylated form of a key oleanolic acid metabolite. This compound serves as a critical reference standard and advanced pharmaceutical intermediate for research and development in medicinal chemistry. It is primarily utilized by pharmaceutical R&D, biotechnology, and academic research institutions focused on developing novel therapeutics based on natural product scaffolds.

Application

• Pharmaceutical Reference Standard: For the qualitative and quantitative analysis (HPLC, LC-MS) of triterpenoid-based drugs and botanical extracts.
• Medicinal Chemistry Intermediate: As a key building block for the semi-synthesis of novel anti-inflammatory, hepatoprotective, or anticancer agents.
• Biochemical Research: For studying the structure-activity relationships (SAR) of pentacyclic triterpenoids and their biological pathways.
• Natural Product Isolation Marker: Used in the identification and purification of related compounds from plant sources like *Ligustrum lucidum*.
• API Development: As a precursor in the development of Active Pharmaceutical Ingredients (APIs) targeting metabolic and inflammatory disorders.
