Tetrabutylammonium bromide (tseem hu ua TBAB), nrog rau cov tshuaj formula (C₄H₉)₄NBr, yog quaternary ammonium ntsev. Nws muaj plaub pawg butyl (C₄H₉) txuas rau lub atom nitrogen, uas nqa cov nqi zoo, thaum cov ion tsis zoo yog cov bromide ion (Br⁻). Nws yog cov hmoov dawb crystalline hmoov, feem ntau muaj purity ntawm 99.0%, thiab muaj thermal stability zoo thiab dej solubility, nrog rau solubility hauv ntau cov kuab tshuaj organic. Nws yog tsuas yog siv raws li theem hloov catalyst nyob rau hauv cov organic synthesis tshuaj, xws li halogen hloov, REDOX cov tshuaj tiv thaiv, N-alkylation, carbene dichloride cov tshuaj tiv thaiv, thiab lwm yam. Hauv qab no yog cov ncauj lus kom ntxaws txog Tetrabutylammonium bromide.
