((sulfonylbis(4,1-phenylene))bis(azanediyl))dimethanesulfinic acid (CAS 144-76-3), molecular formula C14H16N2O6S3 and molecular weight 404.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of ((sulfonylbis(4,1-phenylene))bis(azanediyl))dimethanesulfinic acid (C14H16N2O6S3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
