Chemical Structure

Diethyl Oxalate CAS 95-92-1 chemical structure

Description

The occurrence of Diethyl Oxalate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Diethyl Oxalate (CAS 95-92-1) is a high-purity analytical reference standard with the molecular formula C6H10O4 and a molecular weight of 146.14 g/mol.

The molecular framework of Diethyl Oxalate (C6H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
