Description
CATO manufactures 2,3-Dichloro-5,6-difluorobromobenzene 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.
CATO supplies 2,3-Dichloro-5,6-difluorobromobenzene (CAS 1263377-80-5), a certified reference material (molecular formula C6HBrCl2F2, MW 261.88 g/mol) for analytical method development and quality control.
Based on its molecular formula C6HBrCl2F2, 2,3-Dichloro-5,6-difluorobromobenzene contains fluorine/chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
