Chemical Structure

1-(4-Fluoro-3-nitrophenyl)-1H-pyrrole-2,5-dione CAS 67154-40-9 chemical structure

Description

The occurrence of 1-(4-Fluoro-3-nitrophenyl)-1H-pyrrole-2,5-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Fluoro-3-nitrophenyl)-1H-pyrrole-2,5-dione (CAS 67154-40-9) is a high-purity analytical reference standard with the molecular formula C10H5FN2O4 and a molecular weight of 236.16 g/mol.

1-(4-Fluoro-3-nitrophenyl)-1H-pyrrole-2,5-dione (C10H5FN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
