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 Sodium 4,7-diphenyl-1,10-phenanthroline-3,8-disulfonate.
CATO supplies Sodium 4,7-diphenyl-1,10-phenanthroline-3,8-disulfonate (CAS 482324-38-9), a certified reference material (molecular formula C24H14N2Na2O6S2, MW 536.49 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Sodium 4,7-diphenyl-1,10-phenanthroline-3,8-disulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 536.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Sodium 4,7-diphenyl-1,10-phenanthroline-3,8-disulfonate 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.
