Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
Decane-1,10-diylbis(triphenylphosphonium) bromide (CAS 917-20-4), molecular formula C46H50P2Br and molecular weight 744.76 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Decane-1,10-diylbis(triphenylphosphonium) bromide (C46H50P2Br) 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.
