Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 363.88 g/mol gives 4,5-DIIODO-1H-IMIDAZOLE-2-CARBOXYLIC ACID distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,5-DIIODO-1H-IMIDAZOLE-2-CARBOXYLIC ACID (CAS 1171126-30-9), a certified reference material (molecular formula C4H2I2N2O2, MW 363.88 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 4,5-DIIODO-1H-IMIDAZOLE-2-CARBOXYLIC ACID is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-DIIODO-1H-IMIDAZOLE-2-CARBOXYLIC ACID 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.
