Chemical Structure
Description
2-Bromo-1-cyclopropoxy-3-(trifluoromethyl)benzene (CAS 1243358-20-4) is a high-purity analytical reference standard with the molecular formula C10H8BrF3O and a molecular weight of 281.07 g/mol.
2-Bromo-1-cyclopropoxy-3-(trifluoromethyl)benzene (C10H8BrF3O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
