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 4-Bromo-N-{[4-ethyl-5-(methylsulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide.
4-Bromo-N-{[4-ethyl-5-(methylsulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide (CAS 338794-53-9), molecular formula C12H15BrN4O2S2 and molecular weight 391.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-N-{[4-ethyl-5-(methylsulfanyl)-4H-1,2,4-triazol-3-yl]methyl}benzene-1-sulfonamide (C12H15BrN4O2S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-{[4-ethyl-5-(methylsulfanyl)-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.
