4-(2,4-Difluorobenzoyl)-N,N-dimethyl-1H-pyrrole-2-carboxamide CAS 338404-10-7

Description

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.

4-(2,4-Difluorobenzoyl)-N,N-dimethyl-1H-pyrrole-2-carboxamide (CAS 338404-10-7), molecular formula C14H12F2N2O2 and molecular weight 278.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-(2,4-Difluorobenzoyl)-N,N-dimethyl-1H-pyrrole-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
