Description
CATO supplies 7-(1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)ethyl)-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 303151-83-9), a certified reference material (molecular formula C13H9ClF3N5S, MW 359.76 g/mol) for analytical method development and quality control.
7-(1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)ethyl)-[1,2,4]triazolo[1,5-a]pyrimidine (C13H9ClF3N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine 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), 7-(1-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)ethyl)-[1,2,4]triazolo[1,5-a]pyrimidine 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.
