Compared with other compounds in its class, the molecular weight of 437.34 g/mol gives [4-(Chloromethyl)phenyl]methyl-triphenyl-phosphonium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[4-(Chloromethyl)phenyl]methyl-triphenyl-phosphonium chloride (CAS 880363-94-0), molecular formula C26H23ClPCl and molecular weight 437.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [4-(Chloromethyl)phenyl]methyl-triphenyl-phosphonium chloride (C26H23ClPCl) is characterized by organophosphorus functionality, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), [4-(Chloromethyl)phenyl]methyl-triphenyl-phosphonium chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
