Chemical Structure

Imidazole-d CAS 6745-43-3 chemical structure

Description

The occurrence of Imidazole-d is closely related to deuterium isotope labeling, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Imidazole-d (CAS 6745-43-3) is a high-purity analytical reference standard with the molecular formula C3HD3N2 and a molecular weight of 71.10 g/mol.

Imidazole-d (C3HD3N2) contains deuterium isotope labeling, a nitrile group. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
