Compared with other compounds in its class, the molecular weight of 271.11 g/mol gives 2-(Benzyloxy)-1,4-dichloro-3-fluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(Benzyloxy)-1,4-dichloro-3-fluorobenzene (CAS 1881293-12-4), molecular formula C13H9Cl2FO and molecular weight 271.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H9Cl2FO, 2-(Benzyloxy)-1,4-dichloro-3-fluorobenzene contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
