1,2,3,4,5-pentafluoro-6-(trichloromethyl)benzene 1,2,3,4,5-pentakis(fluoranyl)-6-(trichloromethyl)benzene 778-34-7 A839211 CAS 778-34-7 chemical structure

Description

The occurrence of 1,2,3,4,5-pentafluoro-6-(trichloromethyl)benzene 1,2,3,4,5-pentakis(fluoranyl)-6-(trichloromethyl)benzene 778-34-7 A839211 is closely related to fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2,3,4,5-pentafluoro-6-(trichloromethyl)benzene 1,2,3,4,5-pentakis(fluoranyl)-6-(trichloromethyl)benzene 778-34-7 A839211 (CAS 778-34-7), molecular formula C7Cl3F5 and molecular weight 285.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine/chlorine substitution, an aromatic ring system, 1,2,3,4,5-pentafluoro-6-(trichloromethyl)benzene 1,2,3,4,5-pentakis(fluoranyl)-6-(trichloromethyl)benzene 778-34-7 A839211 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
