Pinacolone Usage And Synthesis
Chemical Propertiescolourless liquid with camphor-like or peppermint-like odour
UsesPinacolone is a precursor to triazolylpinacolone, triadimefon, paclobutrazol, uniconazole and metribuzin. Furthermore, it acts as an intermediate for biologically active products such as antibacterial, antifungal, antiviral and antituberculous products. It is an important ketone in organic chemistry and participates in condensation, hydrogenation and reductive amination reactions.
