Chemical Structure
Description
CATO supplies 3,3'-Diphenyl-[1,1'-binaphthalene]-2,2'-disulfonic acid (CAS 1461736-02-6), a certified reference material (molecular formula C32H22O6S2, MW 566.64 g/mol) for analytical method development and quality control.
The molecular framework of 3,3'-Diphenyl-[1,1'-binaphthalene]-2,2'-disulfonic acid (C32H22O6S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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), 3,3'-Diphenyl-[1,1'-binaphthalene]-2,2'-disulfonic 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.
