Description
CATO manufactures Tributyl(pyren-1-ylmethyl)phosphonium 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.
Tributyl(pyren-1-ylmethyl)phosphonium bromide (CAS 101363-28-4) is a high-purity analytical reference standard with the molecular formula C29H38PBr and a molecular weight of 497.50 g/mol.
The molecular framework of Tributyl(pyren-1-ylmethyl)phosphonium bromide (C29H38PBr) is characterized by organophosphorus functionality, 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 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.
