Chemical Structure

Methyl 3-(2-{[2-(4-fluorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate CAS 477887-62-0 chemical structure

Description

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.

Methyl 3-(2-{[2-(4-fluorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate (CAS 477887-62-0), molecular formula C21H17FN2O4S2 and molecular weight 444.50 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 3-(2-{[2-(4-fluorobenzamido)phenyl]sulfanyl}acetamido)thiophene-2-carboxylate (C21H17FN2O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
