The occurrence of 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide hydrate is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide hydrate (CAS 5470-77-9) is a high-purity analytical reference standard with the molecular formula C9H11N2I and a molecular weight of 274.10 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 1,3-Dimethyl-1H-benzo[d]imidazol-3-ium iodide hydrate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
