4-Bromo-N-{[5-(methylsulfanyl)-4-(prop-2-en-1-yl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide CAS 338794-44-8

Description

4-Bromo-N-{[5-(methylsulfanyl)-4-(prop-2-en-1-yl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide (CAS 338794-44-8) is a high-purity analytical reference standard with the molecular formula C13H15BrN4O2S2 and a molecular weight of 403.32 g/mol.

The molecular framework of 4-Bromo-N-{[5-(methylsulfanyl)-4-(prop-2-en-1-yl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide (C13H15BrN4O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Bromo-N-{[5-(methylsulfanyl)-4-(prop-2-en-1-yl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide 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.
