Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 423.32 g/mol gives (3-Chlorobenzyl)triphenylphosphonium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-Chlorobenzyl)triphenylphosphonium chloride (CAS 32597-92-5), a certified reference material (molecular formula C25H21ClPCl, MW 423.32 g/mol) for analytical method development and quality control.
(3-Chlorobenzyl)triphenylphosphonium chloride (C25H21ClPCl) contains organophosphorus functionality, chlorine substitution, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (3-Chlorobenzyl)triphenylphosphonium chloride 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.
