Praeruptorin A CAS 73069-25-7 chemical structure

Description

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

CATO supplies Praeruptorin A (CAS 73069-25-7), a certified reference material (molecular formula C21H22O7, MW 386.40 g/mol) for analytical method development and quality control.

Praeruptorin A (C21H22O7) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
