Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(5-acetyl-6-methyl-2-oxo-2H-pyran-3-yl)-4-methoxybenzamide.
N-(5-acetyl-6-methyl-2-oxo-2H-pyran-3-yl)-4-methoxybenzamide (CAS 338404-98-1) is a high-purity analytical reference standard with the molecular formula C16H15NO5 and a molecular weight of 301.29 g/mol.
Structurally, N-(5-acetyl-6-methyl-2-oxo-2H-pyran-3-yl)-4-methoxybenzamide (C16H15NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 301.29 g/mol, it falls into the moderately-high-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).
