Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 161.00 g/mol gives 4-Bromo-2-methylfuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2-methylfuran (CAS 24666-43-1), molecular formula C5H5BrO and molecular weight 161.00 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-2-methylfuran (C5H5BrO) contains a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; 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.
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 4-Bromo-2-methylfuran 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.
