Chemical Structure
Description
As a certified reference material (CRM), 3-Methyl-N-(triphenylphosphoranylidene)aniline 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.
3-Methyl-N-(triphenylphosphoranylidene)aniline (CAS 35843-75-5) is a high-purity analytical reference standard with the molecular formula C25H22NP and a molecular weight of 367.42 g/mol.
Based on its molecular formula C25H22NP, 3-Methyl-N-(triphenylphosphoranylidene)aniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 367.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
