Chemical Structure
Description
3-(2-Bromo-5-(trifluoromethyl)phenyl)pyridine (CAS 1443377-31-8), molecular formula C12H7BrF3N and molecular weight 302.09 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-Bromo-5-(trifluoromethyl)phenyl)pyridine (C12H7BrF3N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 3-(2-Bromo-5-(trifluoromethyl)phenyl)pyridine 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.
