Chemical Structure
Description
Methyl (2E)-3-[2-bromo-6-(trifluoromethoxy)phenyl]prop-2-enoate (CAS 1820748-60-4), molecular formula C11H8BrF3O3 and molecular weight 325.08 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl (2E)-3-[2-bromo-6-(trifluoromethoxy)phenyl]prop-2-enoate (C11H8BrF3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
