Chemical Structure

Ethyl phenyl 4-nitrophenethylphosphonate CAS 3384-91-6 chemical structure

Description

As a certified reference material (CRM), Ethyl phenyl 4-nitrophenethylphosphonate 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.

CATO supplies Ethyl phenyl 4-nitrophenethylphosphonate (CAS 3384-91-6), a certified reference material (molecular formula C16H18NO5P, MW 335.29 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl phenyl 4-nitrophenethylphosphonate (C16H18NO5P) is characterized by a flavonoid core, an amide group, a phosphate ester 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
