Chemical Structure

Benzimidazole-4,5,6,7-d4 CAS 64531-29-9 chemical structure

Description

Benzimidazole-4,5,6,7-d4 (CAS 64531-29-9) is a high-purity analytical reference standard with the molecular formula C7H2D4N2 and a molecular weight of 122.16 g/mol.

Structurally, Benzimidazole-4,5,6,7-d4 (C7H2D4N2) contains deuterium isotope labeling, a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 122.16 g/mol, it falls into the low-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.

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.
