Chemical Structure

1-(2-Chloroethyl)-1H-imidazole Hydrochloride CAS 18994-78-0 chemical structure

Description

The occurrence of 1-(2-Chloroethyl)-1H-imidazole Hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(2-Chloroethyl)-1H-imidazole Hydrochloride (CAS 18994-78-0) is a high-purity analytical reference standard with the molecular formula C5H7ClN2HCl and a molecular weight of 167.03 g/mol.

The molecular framework of 1-(2-Chloroethyl)-1H-imidazole Hydrochloride (C5H7ClN2HCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 1-(2-Chloroethyl)-1H-imidazole Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
