Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.96 g/mol gives 1,7-Dibromonaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,7-Dibromonaphthalene (CAS 58258-65-4), a certified reference material (molecular formula C10H6Br2, MW 285.96 g/mol) for analytical method development and quality control.
The molecular framework of 1,7-Dibromonaphthalene (C10H6Br2) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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 1,7-Dibromonaphthalene 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.
