5-Acetyl-2,6-dimethyl-4-(4-nitrophenyl)-1,4-dihydropyridine-3-carboxylic acid CAS 219553-55-6

Description

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.

5-Acetyl-2,6-dimethyl-4-(4-nitrophenyl)-1,4-dihydropyridine-3-carboxylic acid (CAS 219553-55-6) is a high-purity analytical reference standard with the molecular formula C16H16N2O5 and a molecular weight of 316.31 g/mol.

Based on its molecular formula C16H16N2O5, 5-Acetyl-2,6-dimethyl-4-(4-nitrophenyl)-1,4-dihydropyridine-3-carboxylic acid contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 316.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
