Beschreibung

2,5-Diaminobenzenesulfonic acid (DABS) is a chemical compound that can be used to measure the thermal expansion coefficient of solids. It is obtained by the reaction of phosphorus pentoxide with sodium citrate in hydrochloric acid solution. DABS has been used in the development of polymers and other materials. The optimum concentration of DABS for use as a chemical probe depends on the solvent and temperature. The sulfonation of DABS produces 2,5-diamino-6-sulfonic acid (DAS). The DAS can be used to measure peroxidase-like activity in urine samples or magnetic resonance spectroscopy data from polymer films. DAS also reacts with silver ions to form silver sulfide, which can be detected by electrochemical impedance spectroscopy (EIS).
