Product Description:

3-Methyl-2-buten-1-ol, also known as prenol, is an unsaturated primary alcohol with the molecular formula C5H10O. It is a colorless to pale yellow liquid with a characteristic odor. This compound is a key structural unit in organic synthesis, featuring a reactive hydroxyl group and an isoprenoid skeleton. Its primary industrial significance lies in its role as a crucial intermediate in the synthesis of isoprenoids and terpenoids. Most importantly, prenol serves as a fundamental building block for the production of coenzyme Q10 (ubiquinone), a vital compound in cellular energy production and a popular dietary supplement. Furthermore, it is extensively used in the fragrance and flavor industry to impart green, floral, and fruity notes. In material science, its isoprene-like structure makes it a valuable precursor for synthesizing specialized polymers and organic electronic materials, including certain components for OLEDs. As a versatile C5 synthon, it is employed in various chemical reactions, including esterification and etherification. It requires careful handling due to its flammability and potential for causing skin and eye irritation.
