Chemical Structure
Description
Methyl 4-(N-(3-methylbenzo[b]thiophen-2-yl)sulfamoyl)benzoate (C17H15NO4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Methyl 4-(N-(3-methylbenzo[b]thiophen-2-yl)sulfamoyl)benzoate (CAS 1104631-31-3), a certified reference material (molecular formula C17H15NO4S2, MW 361.44 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.
