Chemical Structure
Description
3-(4-((Phenylmethyl)sulfonamido)phenoxy)thiophene-2-carboxylic acid (CAS 882747-64-0) is a high-purity analytical reference standard with the molecular formula C18H15NO5S2 and a molecular weight of 389.45 g/mol.
3-(4-((Phenylmethyl)sulfonamido)phenoxy)thiophene-2-carboxylic acid (C18H15NO5S2) 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).
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.
