Chemical Structure
Description
N-(2-(5-(4-Chlorophenyl)furan-2-carbonyl)-4,5-dimethoxyphenyl)acetamide (CAS 886493-79-4) is a high-purity analytical reference standard with the molecular formula C21H18ClNO5 and a molecular weight of 399.82 g/mol.
Structurally, N-(2-(5-(4-Chlorophenyl)furan-2-carbonyl)-4,5-dimethoxyphenyl)acetamide (C21H18ClNO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 399.82 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
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.
