Praeruptorin B CAS 81740-07-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Praeruptorin B (CAS 81740-07-0), a certified reference material (molecular formula C24H26O7, MW 426.46 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H26O7, Praeruptorin B contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 426.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Praeruptorin B 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.
