Chemical Structure
Description
CATO supplies 1,5-Dibromo-2,3-difluorobenzene (CAS 811713-09-4), a certified reference material (molecular formula C6H2Br2F2, MW 271.88 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H2Br2F2, 1,5-Dibromo-2,3-difluorobenzene contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 1,5-Dibromo-2,3-difluorobenzene 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.
