Chemical Structure
Description
The occurrence of 1-Bromo-3,5-dichlorobenzene is closely related to chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-3,5-dichlorobenzene (CAS 19752-55-7) is a high-purity analytical reference standard with the molecular formula C6H3BrCl2 and a molecular weight of 225.90 g/mol.
Owing to chlorine/bromine substitution, an aromatic ring system, 1-Bromo-3,5-dichlorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-3,5-dichlorobenzene 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.
