Methyl 3-(5-bromothiophene-2-carboxamido)thiophene-2-carboxylate CAS 717866-86-9 chemical structure

Description

The occurrence of Methyl 3-(5-bromothiophene-2-carboxamido)thiophene-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 3-(5-bromothiophene-2-carboxamido)thiophene-2-carboxylate (CAS 717866-86-9), molecular formula C11H8BrNO3S2 and molecular weight 346.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H8BrNO3S2, Methyl 3-(5-bromothiophene-2-carboxamido)thiophene-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 346.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
