Chemical Structure
Description
CATO supplies Triphenyl(4-pyridylmethyl)phosphonium chloride (CAS 73870-25-4), a certified reference material (molecular formula C24H21NPCl, MW 389.86 g/mol) for analytical method development and quality control.
Triphenyl(4-pyridylmethyl)phosphonium chloride (C24H21NPCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, chlorine 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.
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 Triphenyl(4-pyridylmethyl)phosphonium 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.
