Nibintu bya cationic surfactant bifite imiterere myiza ya bagiteri, kandi igice cyingenzi cyibikorwa byabo bya bagiteri ni itsinda rya cationic ryakozwe no guhuza imizi kama na atome ya azote.
2. Kuva mu 1935, igihe Abadage bavumbuye ingaruka za bagiteri ziterwa na gaze ya alkyl dimethyl ammonium, barayikoresheje mu kuvura imyenda ya gisirikare kugirango birinde kwandura ibikomere. Ubushakashatsi bwakozwe kuri quaternary ammonium umunyu antibacterial yamye yibandwaho nabashakashatsi. Ibikoresho bya antibacterial byateguwe hamwe nu munyu wa kane wa amonium umunyu bifite antibacterial nziza kandi birashobora gukoreshwa mubice byinshi nkubuvuzi, kuvura amazi, nibiryo.
3. Imikorere yumunyu wa kane wa amonium irimo:

Fungiside y’ubuhinzi, yanduza ahantu rusange, yanduza amazi yangiza, yangiza imiti y’amazi, yanduza imiti, yanduza amatungo n’inkoko, yanduza imiti itukura, yangiza ubururu bwatsi-icyatsi kibisi, hamwe n’indi mirima yangiza. By'umwihariko umunyu wa Gemini quaternary umunyu wa amonium ufite ingaruka zidasanzwe za bagiteri ndetse nigiciro gito muri rusange.

Tetrabutylammonium bromide (TBAB), bizwi kandi nka tetrabutylammonium bromide。

Numunyu kama hamwe na formulike ya C ₁₆ H.₃₆BrN.

Igicuruzwa cyera ni kirisiti yera cyangwa ifu, hamwe na deliquescence numunuko udasanzwe. Irahagaze mubushyuhe bwicyumba hamwe nigitutu cyikirere. Gushonga mumazi, inzoga, na acetone, gushonga gato muri benzene.

Cikoreshwa cyane nkigihe gito muri synthesis organique, catalizike yo kwimura, na ion couple reagent.
