Description
CATO supplies 5-(3-Bromophenyl)-3-cyclopropyl-1h-1,2,4-triazole (CAS 1251318-38-3), a certified reference material (molecular formula C11H10BrN3, MW 264.12 g/mol) for analytical method development and quality control.
5-(3-Bromophenyl)-3-cyclopropyl-1h-1,2,4-triazole (C11H10BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-(3-Bromophenyl)-3-cyclopropyl-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.
