Chemical Structure

Dopaquinone Sulphate CAS 1797832-49-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Dopaquinone Sulphate (CAS 1797832-49-5) is a high-purity analytical reference standard with the molecular formula C9H9NO4H2O4S and a molecular weight of 293.25 g/mol.

Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Dopaquinone Sulphate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.25 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).

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.
