Chemical Structure
Description
methyl (2E)-3-(5-bromofuran-2-yl)prop-2-enoate (CAS 62157-66-8) is a high-purity analytical reference standard with the molecular formula C8H7BrO3 and a molecular weight of 231.04 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, methyl (2E)-3-(5-bromofuran-2-yl)prop-2-enoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures methyl (2E)-3-(5-bromofuran-2-yl)prop-2-enoate 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.
