1. Quaternary ammonium salts makomisheni anoumbwa nekutsiva ese mana maatomu ehydrogen mumaoni amamoniyamu nemapoka alkyl.

Ivo i cationic surfactant ine yakanakisa bactericidal properties, uye chikamu chinoshanda chebasa ravo rebhakitiriya iboka re cationic rakaumbwa nekubatanidzwa kwemidzi ye organic uye maatomu enitrogen.
2. Kubva muna 1935, vanhu vokuGermany pavakawana utachiona hwealkyl dimethyl ammonium gasification, vakaishandisa kurapa yunifomu dzechiuto kudzivirira utachiona hwemaronda. Tsvagiridzo yequaternary ammonium salt antibacterial zvinhu yagara iri yekutarisisa kwevanoongorora. Antibacterial zvinhu zvakagadzirirwa ne quaternary ammonium salt zvine yakanaka antibacterial properties uye inogona kushandiswa zvakanyanya mundima dzakawanda dzakadai semushonga, kurapwa kwemvura, uye chikafu.
3. Mabasa equaternary ammonium salt anosanganisira:

Zvekurima fungicides, mishonga yeveruzhinji inouraya utachiona, inotenderera mvura inouraya utachiona, aquaculture disinfectants, mishonga yekuuraya utachiona, zvipfuyo nehuku house disinfectants, red tide disinfectants, blue-green algae disinfectants, nedzimwe minda yekuuraya utachiona. Kunyanya Gemini quaternary ammonium munyu ine yakanakisa bactericidal mhedzisiro uye yakaderera mutengo.

Tetrabutylammonium bromide (TBAB), inozivikanwawo se tetrabutylammonium bromide.

Iyo organic munyu ine molecular formula C ₁₆ H₃₆BrN.

Chigadzirwa chakachena ikristaro chena kana hupfu, ine deliquescence uye kunhuhwirira kwakakosha. Yakagadzikana pakupisa kwekamuri uye kumanikidzwa kwemhepo. Soluble mumvura, doro, uye acetone, zvishoma soluble mu benzene.

Commonly inoshandiswa seyepakati mune organic synthesis, chikamu chekufambisa catalyst, uye ion pair reagent.
