Compared with other compounds in its class, the molecular weight of 164.16 g/mol gives 4-Amino-1-methyl-1,3-dihydro-2H-imidazo[4,5-c]pyridin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Amino-1-methyl-1,3-dihydro-2H-imidazo[4,5-c]pyridin-2-one (CAS 71703-04-3) is a high-purity analytical reference standard with the molecular formula C7H8N4O and a molecular weight of 164.16 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Amino-1-methyl-1,3-dihydro-2H-imidazo[4,5-c]pyridin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.16 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
