Description

Pachymic Acid CAS NO 29070-92-6 is a bioactive triterpenoid compound primarily isolated from the medicinal fungus *Poria cocos*. This high-purity reference standard is critical for ensuring analytical accuracy and reproducibility in research and development. It is essential for pharmaceutical, nutraceutical, and academic laboratories focused on natural product chemistry, quality control, and bioactivity studies.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and purity testing of herbal extracts and finished products containing *Poria cocos*.
• Bioactivity Research: Employed in *in vitro* and *in vivo* studies to investigate its reported anti-inflammatory, anti-tumor, neuroprotective, and diuretic properties.
• Natural Product Isolation & Synthesis: Serves as a key marker compound for the standardization of extraction processes and as a starting point for the semi-synthesis of novel derivatives.
• Dietary Supplement QC/QA: Acts as a primary analytical standard to verify label claims and ensure batch-to-batch consistency in nutraceutical formulations.
• Method Development & Validation: Critical for developing and validating robust HPLC, UPLC, and LC-MS/MS analytical methods in compliance with ICH, USP, or EP guidelines.
