Chemical Structure
Description
CATO supplies 3-bromo-1-methyl-5-(2,2,2-trifluoroethyl)-1H-1,2,4-triazole (CAS 2171973-96-7), a certified reference material (molecular formula C5H5BrF3N3, MW 244.01 g/mol) for analytical method development and quality control.
3-bromo-1-methyl-5-(2,2,2-trifluoroethyl)-1H-1,2,4-triazole (C5H5BrF3N3) contains a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-bromo-1-methyl-5-(2,2,2-trifluoroethyl)-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.
