Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-1-(4-chloro-2-fluoro-5-methylphenyl)-1-ethanone (CAS 338982-26-6), molecular formula C9H7BrClFO and molecular weight 265.51 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-1-(4-chloro-2-fluoro-5-methylphenyl)-1-ethanone (C9H7BrClFO) contains a hydroxyl group, an ether linkage, 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.
CATO manufactures 2-Bromo-1-(4-chloro-2-fluoro-5-methylphenyl)-1-ethanone 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.
