n-(Diphenylphosphoryl)-p,p-diphenylphosphinimidic acid CAS 31239-06-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(Diphenylphosphoryl)-p,p-diphenylphosphinimidic acid.

n-(Diphenylphosphoryl)-p,p-diphenylphosphinimidic acid (CAS 31239-06-2) is a high-purity analytical reference standard with the molecular formula C24H21NO2P2 and a molecular weight of 417.38 g/mol.

Structurally, n-(Diphenylphosphoryl)-p,p-diphenylphosphinimidic acid (C24H21NO2P2) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 417.38 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
