Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.94 g/mol gives 1,4-Dibromo-2-vinylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4-Dibromo-2-vinylbenzene (CAS 32917-57-0) is a high-purity analytical reference standard with the molecular formula C8H6Br2 and a molecular weight of 261.94 g/mol.
Owing to bromine substitution, an aromatic ring system, 1,4-Dibromo-2-vinylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.94 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 1,4-Dibromo-2-vinylbenzene 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.
