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.
