Diphenyl benzylphosphoramidate CAS 33985-75-0

Description

The occurrence of Diphenyl benzylphosphoramidate 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.

CATO supplies Diphenyl benzylphosphoramidate (CAS 33985-75-0), a certified reference material (molecular formula C19H18NO3P, MW 339.32 g/mol) for analytical method development and quality control.

The molecular framework of Diphenyl benzylphosphoramidate (C19H18NO3P) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), Diphenyl benzylphosphoramidate 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.
