Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.92 g/mol gives 5-Bromo-2-chlorobenzyl Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromo-2-chlorobenzyl Chloride (CAS 928758-19-4), a certified reference material (molecular formula C7H5BrCl2, MW 239.92 g/mol) for analytical method development and quality control.
Owing to chlorine/bromine substitution, an aromatic ring system, 5-Bromo-2-chlorobenzyl Chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.92 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 5-Bromo-2-chlorobenzyl Chloride 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.
