Chemical Structure
Description
As a certified reference material (CRM), 1-(difluoromethyl)-5-iodo-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.
1-(difluoromethyl)-5-iodo-1H-1,2,4-triazole (CAS 2919671-31-9), molecular formula C3H2F2IN3 and molecular weight 244.97 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/iodine substitution, 1-(difluoromethyl)-5-iodo-1H-1,2,4-triazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 244.97 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.
