Chemical Structure
Description
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.
Quinolinium, 1-ethyl-2-[(1-ethyl-2(1H)-quinolinylidene)methyl]-, chloride (CAS 2402-42-8) is a high-purity analytical reference standard with the molecular formula C23H23N2Cl and a molecular weight of 362.90 g/mol.
Structurally, Quinolinium, 1-ethyl-2-[(1-ethyl-2(1H)-quinolinylidene)methyl]-, chloride (C23H23N2Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 362.90 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
