Chemical Structure

Oxalic Acid Ethyl Ester CAS 617-37-8 chemical structure

Description

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.

CATO supplies Oxalic Acid Ethyl Ester (CAS 617-37-8), a certified reference material (molecular formula C4H6O4, MW 118.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C4H6O4, Oxalic Acid Ethyl Ester contains a carbohydrate-derived structure; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 118.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
