Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 126.11 g/mol gives 1-Methylimidazole-5-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Methylimidazole-5-carboxylic Acid (CAS 41806-40-0), a certified reference material (molecular formula C5H6N2O2, MW 126.11 g/mol) for analytical method development and quality control.
Structurally, 1-Methylimidazole-5-carboxylic Acid (C5H6N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 126.11 g/mol, it falls into the low-molecular-weight range. 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.
As a certified reference material (CRM), 1-Methylimidazole-5-carboxylic Acid 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.
