4-(1,1-Difluoroethyl)biphenyl CAS 1204296-02-5

Description

Compared with other compounds in its class, the molecular weight of 218.24 g/mol gives 4-(1,1-Difluoroethyl)biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(1,1-Difluoroethyl)biphenyl (CAS 1204296-02-5) is a high-purity analytical reference standard with the molecular formula C14H12F2 and a molecular weight of 218.24 g/mol.

Owing to fluorine substitution, a polycyclic aromatic system, 4-(1,1-Difluoroethyl)biphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4-(1,1-Difluoroethyl)biphenyl 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.
