CAS 106-34-3: Quinhydrone

Description: Quinhydrone is a chemical compound that consists of a 1:1 stoichiometric mixture of benzoquinone and hydroquinone. It is typically encountered as a dark brown to black solid, exhibiting a crystalline structure. Quinhydrone is notable for its redox properties, as it can undergo oxidation and reduction reactions, making it useful in various electrochemical applications. The compound is sparingly soluble in water but more soluble in organic solvents such as ethanol and acetone. Quinhydrone is often utilized in the preparation of pH indicators and in the study of electron transfer processes. Its stability can be influenced by environmental factors such as light and temperature, which may lead to degradation over time. Additionally, quinhydrone has applications in the field of analytical chemistry, particularly in the determination of pH and as a reference electrode in potentiometric measurements. Safety precautions should be taken when handling quinhydrone, as it can be harmful if ingested or inhaled, and appropriate protective equipment should be used.
