1-(4-Bromo-2-fluorophenyl)pyrrolidin-2-one CAS 625446-50-6

Description

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.

1-(4-Bromo-2-fluorophenyl)pyrrolidin-2-one (CAS 625446-50-6), molecular formula C10H9BrFNO and molecular weight 258.09 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Bromo-2-fluorophenyl)pyrrolidin-2-one (C10H9BrFNO) 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; 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.
