Chemical Structure

3,4-Dihydroxythiophene-2,5-dicarboxylic acid CAS 14282-58-7 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.

CATO supplies 3,4-Dihydroxythiophene-2,5-dicarboxylic acid (CAS 14282-58-7), a certified reference material (molecular formula C6H4O6S, MW 204.16 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, a sulfone group, 3,4-Dihydroxythiophene-2,5-dicarboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.16 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.
