(2-Ethoxyethyl)diphenylphosphine oxide CAS 4336-75-8

Description

The occurrence of (2-Ethoxyethyl)diphenylphosphine oxide is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2-Ethoxyethyl)diphenylphosphine oxide (CAS 4336-75-8), a certified reference material (molecular formula C16H19O2P, MW 274.29 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H19O2P, (2-Ethoxyethyl)diphenylphosphine oxide contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), (2-Ethoxyethyl)diphenylphosphine oxide 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.
