Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 416.41 g/mol gives Diphenyl ((phenylamino)(pyridin-2-yl)methyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Diphenyl ((phenylamino)(pyridin-2-yl)methyl)phosphonate (CAS 3360-70-1) is a high-purity analytical reference standard with the molecular formula C24H21N2O3P and a molecular weight of 416.41 g/mol.
The molecular framework of Diphenyl ((phenylamino)(pyridin-2-yl)methyl)phosphonate (C24H21N2O3P) is characterized by a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
