Chemical Structure
Description
The occurrence of N-(4-{[3-chloro-4-(pyrimidin-2-yloxy)phenyl]sulfamoyl}phenyl)acetamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(4-{[3-chloro-4-(pyrimidin-2-yloxy)phenyl]sulfamoyl}phenyl)acetamide (CAS 338413-30-2), a certified reference material (molecular formula C18H15ClN4O4S, MW 418.85 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H15ClN4O4S, N-(4-{[3-chloro-4-(pyrimidin-2-yloxy)phenyl]sulfamoyl}phenyl)acetamide contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
