Chemical Structure
Description
The molecular framework of 1-Methyl-4-ureido-1H-imidazole-5-sulfonamide (C5H9N5O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. 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).
1-Methyl-4-ureido-1H-imidazole-5-sulfonamide (CAS 6339-58-8) is a high-purity analytical reference standard with the molecular formula C5H9N5O3S and a molecular weight of 219.22 g/mol.
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-Methyl-4-ureido-1H-imidazole-5-sulfonamide 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.
