Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 488.66 g/mol gives Polygalic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Polygalic acid (CAS 1260-04-4), molecular formula C29H44O6 and molecular weight 488.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Polygalic acid (C29H44O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Polygalic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
