Chemical Structure
Description
(4-Nitrobenzyl)triphenylphosphonium bromide (CAS 2767-70-6), molecular formula C25H21NO2PBr and molecular weight 478.33 g/mol, is a CATO reference standard with documented purity and traceability.
(4-Nitrobenzyl)triphenylphosphonium bromide (C25H21NO2PBr) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-Nitrobenzyl)triphenylphosphonium bromide 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.
