Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2,2',7,7'-Tetrabromospiro[fluorene-9,9'-xanthene] (CAS 1338596-81-8), a certified reference material (molecular formula C25H12Br4O, MW 647.98 g/mol) for analytical method development and quality control.
The molecular framework of 2,2',7,7'-Tetrabromospiro[fluorene-9,9'-xanthene] (C25H12Br4O) is characterized by a steroid core, a hydroxyl group, an ether linkage, bromine substitution. 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 2,2',7,7'-Tetrabromospiro[fluorene-9,9'-xanthene] 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.
