Chemical Structure
Description
The molecular framework of 5-bromo-7-chloro-4-iodo-chromane (C9H7BrClIO) is characterized by a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
5-bromo-7-chloro-4-iodo-chromane (CAS 1934926-33-6), molecular formula C9H7BrClIO and molecular weight 373.41 g/mol, is a CATO reference standard with documented purity and traceability.
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 5-bromo-7-chloro-4-iodo-chromane 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.
