Pinacol

CAS: 76-09-5

Pinacol is a product of the reaction between dimethyl fumarate and pinacol. It is used as a fluorescence probe in the titration calorimetry, which is a technique used to determine the free energy change and enthalpy change of chemical reactions. Pinacol can be used to study the reaction mechanism of various organic compounds, such as halides, ketones, amines, alcohols and esters. Pinacol can also be used for analytical chemistry and flow systems. The hydroxyl group on pinacol reacts with halides and other electron-deficient compounds to form an intramolecular hydrogen bond that stabilizes the molecule. This reaction leads to the formation of an asymmetric synthesis that has a high yield.
