Chemical Structure

Diethyl (diethoxymethyl)phosphonate CAS 17997-33-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 240.23 g/mol gives Diethyl (diethoxymethyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl (diethoxymethyl)phosphonate (CAS 17997-33-0) is a high-purity analytical reference standard with the molecular formula C9H21O5P and a molecular weight of 240.23 g/mol.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl (diethoxymethyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
