Compared with other compounds in its class, the molecular weight of 329.36 g/mol gives 2-Phenethyl-1-(trifluoromethyl)-5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Phenethyl-1-(trifluoromethyl)-5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinoline (CAS 866049-84-5), molecular formula C20H18F3N and molecular weight 329.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Phenethyl-1-(trifluoromethyl)-5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinoline (C20H18F3N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
