Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 150.15 g/mol gives 5-Fluoro-3-methylbenzofuran distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Fluoro-3-methylbenzofuran (CAS 33118-83-1), a certified reference material (molecular formula C9H7FO, MW 150.15 g/mol) for analytical method development and quality control.
5-Fluoro-3-methylbenzofuran (C9H7FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 5-Fluoro-3-methylbenzofuran 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.
