Chemical Structure

5-Methyl-1H-imidazole-4-carboxamide CAS 77421-51-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 125.13 g/mol gives 5-Methyl-1H-imidazole-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methyl-1H-imidazole-4-carboxamide (CAS 77421-51-3), molecular formula C5H7N3O and molecular weight 125.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, 5-Methyl-1H-imidazole-4-carboxamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.13 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 5-Methyl-1H-imidazole-4-carboxamide 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.
