Description
CATO manufactures 1-Bromo-2-fluoro-3-methyl-5-(trifluoromethyl)benzene 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.
1-Bromo-2-fluoro-3-methyl-5-(trifluoromethyl)benzene (CAS 2167794-49-0), molecular formula C8H5BrF4 and molecular weight 257.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-2-fluoro-3-methyl-5-(trifluoromethyl)benzene (C8H5BrF4) is characterized by fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
