2-(2-(Carboxymethoxy)-2-oxoethoxy)-2-oxoacetic acid CAS CATO-C3D-262989 chemical structure

Description

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.

2-(2-(Carboxymethoxy)-2-oxoethoxy)-2-oxoacetic acid (CAS CATO-C3D-262989) is a high-purity analytical reference standard with the molecular formula C6H6O8 and a molecular weight of 206.11 g/mol.

2-(2-(Carboxymethoxy)-2-oxoethoxy)-2-oxoacetic acid (C6H6O8) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
