Chemical Structure
Description
As a certified reference material (CRM), 4-{5-[2-(trifluoromethyl)phenyl]-1,2,4-oxadiazol-3-yl}pyridine 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-{5-[2-(trifluoromethyl)phenyl]-1,2,4-oxadiazol-3-yl}pyridine (CAS 339104-49-3), molecular formula C14H8F3N3O and molecular weight 291.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-{5-[2-(trifluoromethyl)phenyl]-1,2,4-oxadiazol-3-yl}pyridine (C14H8F3N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
