Compared with other compounds in its class, the molecular weight of 213.06 g/mol gives (4-(N,S-Dimethylsulfonimidoyl)phenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-(N,S-Dimethylsulfonimidoyl)phenyl)boronic acid (CAS 2904595-95-3), molecular formula C8H12BNO3S and molecular weight 213.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-(N,S-Dimethylsulfonimidoyl)phenyl)boronic acid (C8H12BNO3S) is characterized by an amide group, a sulfone group, a carboxylic acid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
