Product Details

Product Overview

Usage

Primarily used as a gasoline anti-knock agent to effectively raise the octane number, improve fuel combustion efficiency, reduce engine knock and broaden the ignition limit range of fuel mixtures. Also used as an organic synthesis intermediate in the production of cationic dyes (such as Cationic Brilliant Red FG and Cationic Pink B), and as an acid scavenger and solvent.
