2,4-Difluoro-1-(2,2,2-trifluoroethyl)benzene CAS 1092350-12-3

Description

The occurrence of 2,4-Difluoro-1-(2,2,2-trifluoroethyl)benzene is closely related to fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,4-Difluoro-1-(2,2,2-trifluoroethyl)benzene (CAS 1092350-12-3), molecular formula C8H5F5 and molecular weight 196.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine substitution, an aromatic ring system, 2,4-Difluoro-1-(2,2,2-trifluoroethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
