2-[(3-carboxy-1-oxo-2-propen-1-yl)amino]-5,6-dihydro-4H-Cyclopenta[b]thiophene-3-carboxylic acid, 3-ethyl ester CAS 314282-74-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-[(3-carboxy-1-oxo-2-propen-1-yl)amino]-5,6-dihydro-4H-Cyclopenta[b]thiophene-3-carboxylic acid, 3-ethyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

2-[(3-carboxy-1-oxo-2-propen-1-yl)amino]-5,6-dihydro-4H-Cyclopenta[b]thiophene-3-carboxylic acid, 3-ethyl ester (CAS 314282-74-1) is a high-purity analytical reference standard with the molecular formula C14H15NO5S and a molecular weight of 309.34 g/mol.

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.
