Pinacol（Cat No.:R021277）, also known as 2,3-dimethyl-2,3-butanediol, is a vicinal diol featuring two hydroxyl groups and two methyl groups on adjacent carbon atoms. This symmetrical compound is a colorless crystalline solid with low volatility and good solubility in polar solvents. Pinacol is widely used in organic synthesis, particularly in the formation of pinacolone via the pinacol rearrangement under acidic conditions. It also serves as a chelating ligand, a protecting group for carbonyl compounds, and a precursor for various organometallic reagents. Its stability and reactivity make it valuable in fine chemical and pharmaceutical development.
