Compared with other compounds in its class, the molecular weight of 318.32 g/mol gives 1,1,2,2-Ethanetetracarboxylic acid, tetraethyl ester 1,1,2,2-Tetracarbethoxyethane 632-56-4 NSC2203 NSC693435 Tetraethyl 1,1,2,2-ethanetetracarboxylate Tetrakis(ethoxycarbonyl)ethane tetraethyl ethane-1,1,2,2-tetracarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,1,2,2-Ethanetetracarboxylic acid, tetraethyl ester 1,1,2,2-Tetracarbethoxyethane 632-56-4 NSC2203 NSC693435 Tetraethyl 1,1,2,2-ethanetetracarboxylate Tetrakis(ethoxycarbonyl)ethane tetraethyl ethane-1,1,2,2-tetracarboxylate (CAS 632-56-4), a certified reference material (molecular formula C14H22O8, MW 318.32 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,1,2,2-Ethanetetracarboxylic acid, tetraethyl ester 1,1,2,2-Tetracarbethoxyethane 632-56-4 NSC2203 NSC693435 Tetraethyl 1,1,2,2-ethanetetracarboxylate Tetrakis(ethoxycarbonyl)ethane tetraethyl ethane-1,1,2,2-tetracarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
