4-((4-Ethyl-3-(methoxycarbonyl)-5-methylthiophen-2-yl)amino)-4-oxobutanoic acid CAS 354547-58-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-Ethyl-3-(methoxycarbonyl)-5-methylthiophen-2-yl)amino)-4-oxobutanoic acid.

CATO supplies 4-((4-Ethyl-3-(methoxycarbonyl)-5-methylthiophen-2-yl)amino)-4-oxobutanoic acid (CAS 354547-58-3), a certified reference material (molecular formula C13H17NO5S, MW 299.34 g/mol) for analytical method development and quality control.

4-((4-Ethyl-3-(methoxycarbonyl)-5-methylthiophen-2-yl)amino)-4-oxobutanoic acid (C13H17NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
