Description

Compared with other compounds in its class, the molecular weight of 471.52 g/mol gives N-(1-benzyl-3-cyano-4,5-diphenyl-1H-pyrrol-2-yl)-4-fluorobenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(1-benzyl-3-cyano-4,5-diphenyl-1H-pyrrol-2-yl)-4-fluorobenzamide (CAS 477887-24-4), molecular formula C31H22FN3O and molecular weight 471.52 g/mol, is a CATO reference standard with documented purity and traceability.

N-(1-benzyl-3-cyano-4,5-diphenyl-1H-pyrrol-2-yl)-4-fluorobenzamide (C31H22FN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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 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.
