2-(1,3-Dioxoisoindolin-2-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) CAS 2226728-58-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(1,3-Dioxoisoindolin-2-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V).

2-(1,3-Dioxoisoindolin-2-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (CAS 2226728-58-9), molecular formula C13H16N3O3F6P and molecular weight 407.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-(1,3-Dioxoisoindolin-2-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (C13H16N3O3F6P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate 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. 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.
