n-(1-(5-Chlorothiophen-2-yl)ethyl)thiophene-2-carboxamide CAS 1209448-59-8

Description

Compared with other compounds in its class, the molecular weight of 271.79 g/mol gives n-(1-(5-Chlorothiophen-2-yl)ethyl)thiophene-2-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

n-(1-(5-Chlorothiophen-2-yl)ethyl)thiophene-2-carboxamide (CAS 1209448-59-8) is a high-purity analytical reference standard with the molecular formula C11H10ClNOS2 and a molecular weight of 271.79 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, n-(1-(5-Chlorothiophen-2-yl)ethyl)thiophene-2-carboxamide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 271.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
