Chemical Structure
Description
(1,2-Dichloro-1,2,2-trifluoroethyl)cyclohexane (CAS 219904-98-0) is a high-purity analytical reference standard with the molecular formula C8H11Cl2F3 and a molecular weight of 235.07 g/mol.
Owing to fluorine/chlorine substitution, (1,2-Dichloro-1,2,2-trifluoroethyl)cyclohexane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 235.07 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.
