Description
As a certified reference material (CRM), 3-(Chloromethyl)-4-phenyl-4H-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.
3-(Chloromethyl)-4-phenyl-4H-1,2,4-triazole (CAS 138624-89-2), molecular formula C9H8ClN3 and molecular weight 193.63 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Chloromethyl)-4-phenyl-4H-1,2,4-triazole (C9H8ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
