Diphenyl ((phenylamino)(pyridin-4-yl)methyl)phosphonate CAS 3360-72-3

Description

The occurrence of Diphenyl ((phenylamino)(pyridin-4-yl)methyl)phosphonate is closely related to a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diphenyl ((phenylamino)(pyridin-4-yl)methyl)phosphonate (CAS 3360-72-3) is a high-purity analytical reference standard with the molecular formula C24H21N2O3P and a molecular weight of 416.41 g/mol.

Structurally, Diphenyl ((phenylamino)(pyridin-4-yl)methyl)phosphonate (C24H21N2O3P) contains a steroid core, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 416.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
