Description
As a certified reference material (CRM), 4-(2-Fluorophenyl)-2,5-dimethyl-2,4-dihydro-3H-1,2,4-triazol-3-one 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.
4-(2-Fluorophenyl)-2,5-dimethyl-2,4-dihydro-3H-1,2,4-triazol-3-one (CAS 860789-15-7) is a high-purity analytical reference standard with the molecular formula C10H10FN3O and a molecular weight of 207.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(2-Fluorophenyl)-2,5-dimethyl-2,4-dihydro-3H-1,2,4-triazol-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
