Chemical Structure

Thonningianin A CAS 271579-11-4 chemical structure

Description

CATO supplies Thonningianin A (CAS 271579-11-4), a certified reference material (molecular formula C42H34O21, MW 874.71 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Thonningianin A is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 874.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Thonningianin 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.
