Chemical Structure

Diethyl (4-chlorobenzyl)phosphonate CAS 39225-17-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 262.67 g/mol gives Diethyl (4-chlorobenzyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Diethyl (4-chlorobenzyl)phosphonate (CAS 39225-17-7), a certified reference material (molecular formula C11H16ClO3P, MW 262.67 g/mol) for analytical method development and quality control.

Structurally, Diethyl (4-chlorobenzyl)phosphonate (C11H16ClO3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 262.67 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
