Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 327.17 g/mol gives Ethyl 5-bromo-4-ethoxy-3-methylbenzofuran-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 5-bromo-4-ethoxy-3-methylbenzofuran-2-carboxylate (CAS 1403566-77-7) is a high-purity analytical reference standard with the molecular formula C14H15BrO4 and a molecular weight of 327.17 g/mol.
The molecular framework of Ethyl 5-bromo-4-ethoxy-3-methylbenzofuran-2-carboxylate (C14H15BrO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 5-bromo-4-ethoxy-3-methylbenzofuran-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.
