Chemical Structure

Ethyl 3-amino-7-bromo-5-chlorobenzofuran-2-carboxylate CAS 2183997-56-8 chemical structure

Description

The occurrence of Ethyl 3-amino-7-bromo-5-chlorobenzofuran-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 3-amino-7-bromo-5-chlorobenzofuran-2-carboxylate (CAS 2183997-56-8) is a high-purity analytical reference standard with the molecular formula C11H9BrClNO3 and a molecular weight of 318.55 g/mol.

Based on its molecular formula C11H9BrClNO3, Ethyl 3-amino-7-bromo-5-chlorobenzofuran-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.55 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.

As a certified reference material (CRM), Ethyl 3-amino-7-bromo-5-chlorobenzofuran-2-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.
