Description

19β-Hydroxy-3-Oxolup-20(30)-En-28-Oic Acid 28,19-Lactone is a high-purity, specialized triterpenoid lactone compound of significant interest in advanced research and development. This compound serves as a critical intermediate and reference standard for the synthesis and study of bioactive natural product derivatives. It is primarily sought by pharmaceutical R&D laboratories, academic research institutions, and fine chemical manufacturers focused on developing novel therapeutic agents, particularly in areas like anti-inflammatory and metabolic research.

Application

• Pharmaceutical Intermediate: A key building block for the semi-synthesis of novel lupane-type triterpenoid derivatives with potential pharmacological activity.
• Reference Standard: Used as a certified reference material (CRM) in analytical laboratories for quality control and method validation of related natural products.
• Biochemical Research: Employed in academic and industrial research to study structure-activity relationships (SAR) and biological pathways involving pentacyclic triterpenes.
• Natural Product Chemistry: Serves as a precursor for the preparation of more complex natural analogs for screening in drug discovery programs.
• Fine Chemical Synthesis: Utilized in multi-step organic syntheses requiring a defined stereochemistry and functional group array provided by the lupane skeleton.
