Chemical Structure
Description
4-Butoxy-1-chloro-2-(trifluoromethyl)benzene (CAS 1881290-31-8), molecular formula C11H12ClF3O and molecular weight 252.66 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H12ClF3O, 4-Butoxy-1-chloro-2-(trifluoromethyl)benzene 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 252.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
