Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4',4'',4'''-Methanetetrayltetrabenzenesulfonic acid.
CATO supplies 4,4',4'',4'''-Methanetetrayltetrabenzenesulfonic acid (CAS 1042222-34-3), a certified reference material (molecular formula C25H20O12S4, MW 640.68 g/mol) for analytical method development and quality control.
4,4',4'',4'''-Methanetetrayltetrabenzenesulfonic acid (C25H20O12S4) contains a flavonoid core, a sulfone group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 4,4',4'',4'''-Methanetetrayltetrabenzenesulfonic acid 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.
