Chemical Structure

Bis(phenylsulfonyl)sulfur dimide CAS 667-20-9 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 Bis(phenylsulfonyl)sulfur dimide.

Bis(phenylsulfonyl)sulfur dimide (CAS 667-20-9), molecular formula C12H10N2O4S3 and molecular weight 342.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Bis(phenylsulfonyl)sulfur dimide (C12H10N2O4S3) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
