Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 4-(2-((4-chlorophenyl)sulfonyl)acetamido)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies Ethyl 4-(2-((4-chlorophenyl)sulfonyl)acetamido)benzoate (CAS 895467-50-2), a certified reference material (molecular formula C17H16ClNO5S, MW 381.83 g/mol) for analytical method development and quality control.
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.
