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 Tributyl(4-cyanobenzyl)phosphoniumbromide.
Tributyl(4-cyanobenzyl)phosphoniumbromide (CAS 140141-42-0) is a high-purity analytical reference standard with the molecular formula C20H33NPBr and a molecular weight of 398.37 g/mol.
Tributyl(4-cyanobenzyl)phosphoniumbromide (C20H33NPBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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 Tributyl(4-cyanobenzyl)phosphoniumbromide 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.
