Compared with other compounds in its class, the molecular weight of 183.21 g/mol gives Ethyl 4-amino-1,2-dimethyl-1H-imidazole-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-amino-1,2-dimethyl-1H-imidazole-5-carboxylate (CAS 55747-02-9) is a high-purity analytical reference standard with the molecular formula C8H13N3O2 and a molecular weight of 183.21 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ethyl 4-amino-1,2-dimethyl-1H-imidazole-5-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.21 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 4-amino-1,2-dimethyl-1H-imidazole-5-carboxylate 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.
