    Industry Applications

    • Tertiary Amyl Benzene (TAB) is a vital intermediate chemical for the production of 2-amyl anthraquinone (2-AAQ), which is used as a catalyst for mass production of hydrogen peroxide (H2O2).
    • Tertiary Amyl Benzene is a crucial component of the electrolytes in Lithium-ion batteries. TAB prevents the overcharging in these batteries, thereby helping to eliminate the dangers of fire and explosion associated with over charging.
    • TAB is a key chemical component for the synthesis of an API that has antifungal properties and is used in numerous pharmaceutical synthesis processes.
