Chemical Structure
Description
5-(Cyanomethyl)-3-(difluoromethyl)-4-fluoropicolinonitrile (C9H4F3N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
5-(Cyanomethyl)-3-(difluoromethyl)-4-fluoropicolinonitrile (CAS 1806844-00-7), molecular formula C9H4F3N3 and molecular weight 211.14 g/mol, is a CATO reference standard with documented purity and traceability.
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), 5-(Cyanomethyl)-3-(difluoromethyl)-4-fluoropicolinonitrile 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.
