4-((3-(Methoxycarbonyl)-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)amino)-4-oxobutanoic acid CAS 328025-47-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((3-(Methoxycarbonyl)-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)amino)-4-oxobutanoic acid.

CATO supplies 4-((3-(Methoxycarbonyl)-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)amino)-4-oxobutanoic acid (CAS 328025-47-4), a certified reference material (molecular formula C13H15NO5S, MW 297.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H15NO5S, 4-((3-(Methoxycarbonyl)-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)amino)-4-oxobutanoic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
