Description
CATO manufactures (4-bromo-3-fluoro-phenyl)methyl methanesulfonate 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.
(4-bromo-3-fluoro-phenyl)methyl methanesulfonate (CAS 1240286-88-7), molecular formula C8H14BrFO3S and molecular weight 289.16 g/mol, is a CATO reference standard with documented purity and traceability.
(4-bromo-3-fluoro-phenyl)methyl methanesulfonate (C8H14BrFO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
