Used as a solvent in laboratories and industry, particularly for resins, waxes, and essential oils due to its ability to mix with both polar and nonpolar substances. Commonly employed as a reaction medium in organic synthesis where a tertiary alcohol is needed. Serves as an octane booster in gasoline when used as an oxygenate additive, improving combustion efficiency and reducing emissions. Utilized in the production of perfumes and flavorings as a carrier solvent. Also used in the preparation of tert-butyl chloride and other tert-butyl compounds. In biochemical applications, it acts as a cryoprotectant in the preservation of biological samples. Frequently used in liquid chromatography as a mobile phase component due to its low UV absorbance and suitable elution strength.
