Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 354.40 g/mol gives Triphenyl(pyridin-2-ylmethyl)phosphonium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Triphenyl(pyridin-2-ylmethyl)phosphonium (CAS 71897-61-5), molecular formula C24H21NP and molecular weight 354.40 g/mol, is a CATO reference standard with documented purity and traceability.
Triphenyl(pyridin-2-ylmethyl)phosphonium (C24H21NP) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Triphenyl(pyridin-2-ylmethyl)phosphonium 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.
