Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-bromo-3-methyl-4-(prop-2-yn-1-yloxy)benzofuran-2-carboxylate.
CATO supplies Ethyl 5-bromo-3-methyl-4-(prop-2-yn-1-yloxy)benzofuran-2-carboxylate (CAS 1403564-28-2), a certified reference material (molecular formula C15H13BrO4, MW 337.17 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H13BrO4, Ethyl 5-bromo-3-methyl-4-(prop-2-yn-1-yloxy)benzofuran-2-carboxylate contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.17 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.
CATO manufactures Ethyl 5-bromo-3-methyl-4-(prop-2-yn-1-yloxy)benzofuran-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
