3-(3,4-Dimethoxyphenyl)-3-((4-methylphenyl)sulfonamido)propanoic acid (C18H21NO6S) 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 3-(3,4-Dimethoxyphenyl)-3-((4-methylphenyl)sulfonamido)propanoic acid (CAS 332052-67-2), a certified reference material (molecular formula C18H21NO6S, MW 379.43 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.
