Description
4-((5-Aminopentyl)amino)-2-(2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione 2,2,2-trifluoroacetate (CAS 2093386-40-2), molecular formula C18H22N4O4C2HF3O2 and molecular weight 472.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((5-Aminopentyl)amino)-2-(2,6-dioxopiperidin-3-yl)isoindoline-1,3-dione 2,2,2-trifluoroacetate (C18H22N4O4C2HF3O2) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
