Chemical Structure

Diethyl (2-oxobutyl)phosphonate CAS 1067-73-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl (2-oxobutyl)phosphonate.

CATO supplies Diethyl (2-oxobutyl)phosphonate (CAS 1067-73-8), a certified reference material (molecular formula C8H17O4P, MW 208.19 g/mol) for analytical method development and quality control.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl (2-oxobutyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 208.19 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.

As a certified reference material (CRM), Diethyl (2-oxobutyl)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.
