The occurrence of N-(4-Butoxy-6-(4-fluorophenyl)pyrido[3,2-d]pyrimidin-2-yl)acetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-Butoxy-6-(4-fluorophenyl)pyrido[3,2-d]pyrimidin-2-yl)acetamide (CAS 897362-33-3) is a high-purity analytical reference standard with the molecular formula C19H19FN4O2 and a molecular weight of 354.38 g/mol.
Based on its molecular formula C19H19FN4O2, N-(4-Butoxy-6-(4-fluorophenyl)pyrido[3,2-d]pyrimidin-2-yl)acetamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 354.38 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).
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.
