Chemical Structure
Description
2,5-Dichloro-4-fluorophenacyl bromide (CAS 1803766-10-0) is a high-purity analytical reference standard with the molecular formula C8H4BrCl2FO and a molecular weight of 285.93 g/mol.
2,5-Dichloro-4-fluorophenacyl bromide (C8H4BrCl2FO) 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.
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 2,5-Dichloro-4-fluorophenacyl bromide 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.
