Chemical Structure
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.
4-Bromo-2-methyl-5-oxo-2,5-dihydrofuran-3-yl hexanoate (CAS 61222-87-5) is a high-purity analytical reference standard with the molecular formula C11H15BrO4 and a molecular weight of 291.14 g/mol.
4-Bromo-2-methyl-5-oxo-2,5-dihydrofuran-3-yl hexanoate (C11H15BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-Bromo-2-methyl-5-oxo-2,5-dihydrofuran-3-yl hexanoate 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.
