Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.38 g/mol gives Poliothyrsoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Poliothyrsoside (CAS 18463-25-7), a certified reference material (molecular formula C20H22O9, MW 406.38 g/mol) for analytical method development and quality control.
Structurally, Poliothyrsoside (C20H22O9) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 406.38 g/mol, it falls into the moderately-high-molecular-weight range. 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), Poliothyrsoside 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.
