Description

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.

Ethyl 2-amino-6-bromo-7-ethoxybenzo[b]thiophene-3-carboxylate (CAS 299962-53-1) is a high-purity analytical reference standard with the molecular formula C13H14BrNO3S and a molecular weight of 344.22 g/mol.

Based on its molecular formula C13H14BrNO3S, Ethyl 2-amino-6-bromo-7-ethoxybenzo[b]thiophene-3-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 344.22 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.

As a certified reference material (CRM), Ethyl 2-amino-6-bromo-7-ethoxybenzo[b]thiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
