2-{5-oxo-4-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-1-yl}acetonitrile CAS 343373-32-0

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

2-{5-oxo-4-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-1-yl}acetonitrile (CAS 343373-32-0) is a high-purity analytical reference standard with the molecular formula C11H7F3N4O and a molecular weight of 268.19 g/mol.

2-{5-oxo-4-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-1-yl}acetonitrile (C11H7F3N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2-{5-oxo-4-[3-(trifluoromethyl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-1-yl}acetonitrile 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.
