Chemical Structure

Pinostilbenoside CAS 58762-96-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 404.41 g/mol gives Pinostilbenoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pinostilbenoside (CAS 58762-96-2), molecular formula C21H24O8 and molecular weight 404.41 g/mol, is a CATO reference standard with documented purity and traceability.

Pinostilbenoside (C21H24O8) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Pinostilbenoside 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.
