Description

3β-Acetoxy-12-Oxo-13-Hydroxyoleanan-28-Oic Acid 28,13-Lactone is a high-purity, structurally defined pentacyclic triterpenoid derivative. This compound serves as a critical advanced intermediate and reference standard for pharmaceutical research and development, particularly in the synthesis of bioactive molecules. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and academic research sectors who require well-characterized chemical building blocks.

Application

• Pharmaceutical Intermediate: A key synthetic precursor for the development of novel triterpenoid-based therapeutics targeting inflammation, metabolic disorders, and oncology.
• Reference Standard: Used in analytical laboratories for the qualitative and quantitative analysis (e.g., via HPLC, LC-MS) of complex natural product extracts and finished products.
• Biochemical Research: Employed as a tool compound in pharmacological studies to investigate structure-activity relationships (SAR) and biological pathways involving triterpenoids.
• Natural Product Synthesis: Serves as a starting material or intermediate in the semi-synthesis of complex natural products and their analogs for drug discovery programs.
• Quality Control: Acts as a certified reference material (CRM) to ensure the identity, purity, and potency of raw materials and active pharmaceutical ingredients (APIs) derived from oleanane-type triterpenes.
