Chemical Structure
Description
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.
CATO supplies Benzamide, 4-bromo-3-ethoxy-N-[2-(methylsulfonyl)ethyl]- (CAS 1309682-54-9), a certified reference material (molecular formula C12H16BrNO4S, MW 350.23 g/mol) for analytical method development and quality control.
The molecular framework of Benzamide, 4-bromo-3-ethoxy-N-[2-(methylsulfonyl)ethyl]- (C12H16BrNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
