Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-9-methyl-9-phenyl-9H-fluorene.
4-Bromo-9-methyl-9-phenyl-9H-fluorene (CAS 1548450-59-4), molecular formula C20H15Br and molecular weight 335.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-9-methyl-9-phenyl-9H-fluorene (C20H15Br) 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.
CATO manufactures 4-Bromo-9-methyl-9-phenyl-9H-fluorene 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.
