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.
R-(+)-Cibenzoline-D4 (CAS CATO-C3D-262640) is a high-purity analytical reference standard with the molecular formula C18H14D4N2 and a molecular weight of 266.37 g/mol.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, R-(+)-Cibenzoline-D4 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.37 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).
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.
