Chemical Structure

N-ethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide CAS 551920-77-5 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, N-ethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.29 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).

CATO supplies N-ethyl-3-(1H-pyrrol-1-yl)thiophene-2-carboxamide (CAS 551920-77-5), a certified reference material (molecular formula C11H12N2OS, MW 220.29 g/mol) for analytical method development and quality control.

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.
