Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2’,7’-Dibromospiro[cyclopent[3]ene-1,9’-fluorene] (CAS 951884-04-1), molecular formula C17H12Br2 and molecular weight 376.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2’,7’-Dibromospiro[cyclopent[3]ene-1,9’-fluorene] (C17H12Br2) 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).
CATO manufactures 2’,7’-Dibromospiro[cyclopent[3]ene-1,9’-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.
