2-Chloro-1<I>H</I>-imidazole CAS 16265-04-6 chemical structure

Description

CATO manufactures 2-Chloro-1<I>H</I>-imidazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

2-Chloro-1<I>H</I>-imidazole (CAS 16265-04-6), molecular formula C3H7ClN2 and molecular weight 106.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Chloro-1<I>H</I>-imidazole (C3H7ClN2) is characterized by 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. 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.
