Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 267.92 g/mol gives 1,2-Dibromo-5-fluoro-3-methylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,2-Dibromo-5-fluoro-3-methylbenzene (CAS 1000576-64-6), a certified reference material (molecular formula C7H5Br2F, MW 267.92 g/mol) for analytical method development and quality control.
1,2-Dibromo-5-fluoro-3-methylbenzene (C7H5Br2F) contains fluorine/bromine 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. 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 1,2-Dibromo-5-fluoro-3-methylbenzene 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.
