Chemical Structure

Diethyl (3-oxobutan-2-yl)phosphonate CAS 1066-91-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 208.19 g/mol gives Diethyl (3-oxobutan-2-yl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Diethyl (3-oxobutan-2-yl)phosphonate (CAS 1066-91-7), molecular formula C8H17O4P and molecular weight 208.19 g/mol, is a CATO reference standard with documented purity and traceability.

Diethyl (3-oxobutan-2-yl)phosphonate (C8H17O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
