Tetrabutylammonium is a quaternary ammonium cation with the formula [N(C₄H₉)₄]⁺, also denoted [NBu₄]⁺ (where Bu = butyl group). It is used in the research laboratory to prepare lipophilic salts of inorganic anions. Relative to tetraethylammonium derivatives, tetrabutylammonium salts are more lipophilic but crystallize less readily. It is useful for phase-transfer catalysis.
