3-Bromo-1-[3-(trifluoromethoxy)phenyl]pyrrolidin-2-one CAS 174890-36-9 chemical structure

Description

The occurrence of 3-Bromo-1-[3-(trifluoromethoxy)phenyl]pyrrolidin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Bromo-1-[3-(trifluoromethoxy)phenyl]pyrrolidin-2-one (CAS 174890-36-9), molecular formula C11H9BrF3NO2 and molecular weight 324.09 g/mol, is a CATO reference standard with documented purity and traceability.

3-Bromo-1-[3-(trifluoromethoxy)phenyl]pyrrolidin-2-one (C11H9BrF3NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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 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.
