4-Bromotetraphene CAS 61921-39-9 chemical structure

Description

CATO manufactures 4-Bromotetraphene 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.

CATO supplies 4-Bromotetraphene (CAS 61921-39-9), a certified reference material (molecular formula C18H11Br, MW 307.18 g/mol) for analytical method development and quality control.

The molecular framework of 4-Bromotetraphene (C18H11Br) is characterized by bromine substitution, a polycyclic aromatic 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.
