Chemical Structure
Description
2,3-Dibromo-1-chloro-5-fluoro-4-methylbenzene (CAS 1365969-01-2), molecular formula C7H4Br2ClF and molecular weight 302.37 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dibromo-1-chloro-5-fluoro-4-methylbenzene (C7H4Br2ClF) contains fluorine/chlorine/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 2,3-Dibromo-1-chloro-5-fluoro-4-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.
