Chemical Structure
Description
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.
N-(2-(Dicyclohexylphosphino)benzylidene)cyclohexanamine (CAS 820964-95-2), molecular formula C25H38NP and molecular weight 383.55 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C25H38NP, N-(2-(Dicyclohexylphosphino)benzylidene)cyclohexanamine 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 383.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
