Chemical Structure
Description
N-[2-(2-Chlorobenzenesulfonamido)ethyl]-2,5-bis(2,2,2-trifluoroethoxy)benzamide (CAS 338404-60-7), molecular formula C19H17ClF6N2O5S and molecular weight 534.86 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H17ClF6N2O5S, N-[2-(2-Chlorobenzenesulfonamido)ethyl]-2,5-bis(2,2,2-trifluoroethoxy)benzamide contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 534.86 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.
