Diethyl (2,5-dioxo-2,5-dihydro-1H-imidazol-4-yl)phosphonate CAS 95378-36-2

Description

The occurrence of Diethyl (2,5-dioxo-2,5-dihydro-1H-imidazol-4-yl)phosphonate is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diethyl (2,5-dioxo-2,5-dihydro-1H-imidazol-4-yl)phosphonate (CAS 95378-36-2), molecular formula C7H11N2O5P and molecular weight 234.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Diethyl (2,5-dioxo-2,5-dihydro-1H-imidazol-4-yl)phosphonate (C7H11N2O5P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
