2',5'-Difluoro-[1,1':4',1"-terphenyl]-4,4"-dicarbonitrile CAS 1685285-13-5

Description

2',5'-Difluoro-[1,1':4',1"-terphenyl]-4,4"-dicarbonitrile (C20H10F2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2',5'-Difluoro-[1,1':4',1"-terphenyl]-4,4"-dicarbonitrile (CAS 1685285-13-5), molecular formula C20H10F2N2 and molecular weight 316.30 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 2',5'-Difluoro-[1,1':4',1"-terphenyl]-4,4"-dicarbonitrile 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.
