Chemical Structure

Disodium salt of 3,3 '- (Phenylphosphine diyl) di Benzenesulfonic acid CAS 64018-22-0 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 Disodium salt of 3,3 '- (Phenylphosphine diyl) di Benzenesulfonic acid.

CATO supplies Disodium salt of 3,3 '- (Phenylphosphine diyl) di Benzenesulfonic acid (CAS 64018-22-0), a certified reference material (molecular formula C18H13O6PS2Na, MW 443.38 g/mol) for analytical method development and quality control.

The molecular framework of Disodium salt of 3,3 '- (Phenylphosphine diyl) di Benzenesulfonic acid (C18H13O6PS2Na) is characterized by a flavonoid core, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Disodium salt of 3,3 '- (Phenylphosphine diyl) di Benzenesulfonic 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.
