Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,4-Difluoro-a-(1H-1,2,4-triazolyl)acetophenone-d2 (CAS 1124197-63-2), a certified reference material (molecular formula C10H5D2F2N3O, MW 225.19 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2,4-Difluoro-a-(1H-1,2,4-triazolyl)acetophenone-d2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2,4-Difluoro-a-(1H-1,2,4-triazolyl)acetophenone-d2 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.
