Diethyl (4-methoxybenzyl)phosphonate CAS 1145-93-3

Description

Compared with other compounds in its class, the molecular weight of 258.25 g/mol gives Diethyl (4-methoxybenzyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl (4-methoxybenzyl)phosphonate (CAS 1145-93-3), molecular formula C12H19O4P and molecular weight 258.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl (4-methoxybenzyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Diethyl (4-methoxybenzyl)phosphonate 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.
