The occurrence of 1-(2-Chloro-1,1,2-trifluoroethoxy)-2-methylbenzene is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-Chloro-1,1,2-trifluoroethoxy)-2-methylbenzene (CAS 349-07-5), molecular formula C9H8ClF3O and molecular weight 224.61 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Chloro-1,1,2-trifluoroethoxy)-2-methylbenzene (C9H8ClF3O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
