Methyl 3-Amino-5-(4-chlorophenyl)thiophene-2-carboxylate CAS 91076-93-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 267.73 g/mol gives Methyl 3-Amino-5-(4-chlorophenyl)thiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 3-Amino-5-(4-chlorophenyl)thiophene-2-carboxylate (CAS 91076-93-6), a certified reference material (molecular formula C12H10ClNO2S, MW 267.73 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H10ClNO2S, Methyl 3-Amino-5-(4-chlorophenyl)thiophene-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.73 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).

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.
