Methyl 2-(2-(2,4-dichlorophenoxy)acetamido)-5-((4-ethoxyphenyl)carbamoyl)-4-methylthiophene-3-carboxylate CAS 505095-40-9 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.

Methyl 2-(2-(2,4-dichlorophenoxy)acetamido)-5-((4-ethoxyphenyl)carbamoyl)-4-methylthiophene-3-carboxylate (CAS 505095-40-9) is a high-purity analytical reference standard with the molecular formula C24H22Cl2N2O6S and a molecular weight of 537.41 g/mol.

Methyl 2-(2-(2,4-dichlorophenoxy)acetamido)-5-((4-ethoxyphenyl)carbamoyl)-4-methylthiophene-3-carboxylate (C24H22Cl2N2O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).

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.
