Chemical Structure
Description
Triphenyl(pyridin-2-ylmethyl)phosphonium bromide (CAS 73870-22-1), molecular formula C24H21NPBr and molecular weight 434.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Triphenyl(pyridin-2-ylmethyl)phosphonium bromide (C24H21NPBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 434.32 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 bromide 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.
