Chemical Structure
Description
As a certified reference material (CRM), (1R)-[1,1'-Binaphthalene]-2,2'-disulfonyl dichloride 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.
(1R)-[1,1'-Binaphthalene]-2,2'-disulfonyl dichloride (CAS 1187629-43-1), molecular formula C20H12Cl2O4S2 and molecular weight 451.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1R)-[1,1'-Binaphthalene]-2,2'-disulfonyl dichloride (C20H12Cl2O4S2) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
