Chemical Structure
Description
CATO supplies 4,5-Dibromo-1-methyl-1H-imidazole-2-carbaldehyde (CAS 79326-92-4), a certified reference material (molecular formula C5H4Br2N2O, MW 267.91 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4,5-Dibromo-1-methyl-1H-imidazole-2-carbaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.91 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 4,5-Dibromo-1-methyl-1H-imidazole-2-carbaldehyde 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.
