Chemical Structure
Description
CATO supplies 5-Bromo-6-iodo-1,2-dihydroacenaphthylene (CAS 55157-87-4), a certified reference material (molecular formula C12H8BrI, MW 359.00 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-6-iodo-1,2-dihydroacenaphthylene (C12H8BrI) is characterized by bromine/iodine 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).
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-6-iodo-1,2-dihydroacenaphthylene 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.
