Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.94 g/mol gives Dibromostyrene (unspecified bromination) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dibromostyrene (unspecified bromination) (CAS 31780-26-4) is a high-purity analytical reference standard with the molecular formula C8H6Br2 and a molecular weight of 261.94 g/mol.
The molecular framework of Dibromostyrene (unspecified bromination) (C8H6Br2) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Dibromostyrene (unspecified bromination) 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.
