Chemical Structure

2-iodo-5-methyl-1H-imidazole CAS 73746-43-7 chemical structure

Description

As a certified reference material (CRM), 2-iodo-5-methyl-1H-imidazole 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.

2-iodo-5-methyl-1H-imidazole (CAS 73746-43-7) is a high-purity analytical reference standard with the molecular formula C4H9IN2 and a molecular weight of 212.03 g/mol.

The molecular framework of 2-iodo-5-methyl-1H-imidazole (C4H9IN2) is characterized by iodine 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
