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 3,5-Dibromo-1-(((4-chlorophenyl)sulfonyl)methyl)-1H-1,2,4-triazole.
3,5-Dibromo-1-(((4-chlorophenyl)sulfonyl)methyl)-1H-1,2,4-triazole (CAS 320424-30-4), molecular formula C9H6Br2ClN3O2S and molecular weight 415.49 g/mol, is a CATO reference standard with documented purity and traceability.
3,5-Dibromo-1-(((4-chlorophenyl)sulfonyl)methyl)-1H-1,2,4-triazole (C9H6Br2ClN3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 3,5-Dibromo-1-(((4-chlorophenyl)sulfonyl)methyl)-1H-1,2,4-triazole 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.
