Chemical Structure
Description
1-Bromo-2-chloro-3,5-difluorobenzene (CAS 187929-82-4) is a high-purity analytical reference standard with the molecular formula C6H2BrClF2 and a molecular weight of 227.43 g/mol.
Owing to fluorine/chlorine/bromine substitution, an aromatic ring system, 1-Bromo-2-chloro-3,5-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 227.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1-Bromo-2-chloro-3,5-difluorobenzene 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.
