2-Acetamido-5-bromothiophene-3-carboxylic acid CAS 1160474-66-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 264.10 g/mol gives 2-Acetamido-5-bromothiophene-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Acetamido-5-bromothiophene-3-carboxylic acid (CAS 1160474-66-7), molecular formula C7H6BrNO3S and molecular weight 264.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6BrNO3S, 2-Acetamido-5-bromothiophene-3-carboxylic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
