Compared with other compounds in its class, the molecular weight of 406.50 g/mol gives 4-Methyl-N-(phenyl(5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)carbamoyl)benzenesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Methyl-N-(phenyl(5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)carbamoyl)benzenesulfonamide (CAS 866042-01-5), a certified reference material (molecular formula C16H14N4O3S3, MW 406.50 g/mol) for analytical method development and quality control.
The molecular framework of 4-Methyl-N-(phenyl(5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)carbamoyl)benzenesulfonamide (C16H14N4O3S3) 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 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.
As a certified reference material (CRM), 4-Methyl-N-(phenyl(5-thioxo-4,5-dihydro-1,3,4-thiadiazol-2-yl)carbamoyl)benzenesulfonamide 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.
