Tetra-n-butylammonium bromide (TBAB) bụ ihennu ammonium nke anọihe mejupụtara ya na ngwa ndị metụtara ọtụtụ ubi:
1. Njikọta ihe ndị sitere n'okike
TBABa na-ejikarị eme ihe dị kaihe mkpali mbufe nke usoroiji kwalite mbufe na mgbanwe nke ndị na-eme ihe n'ime sistemụ mmeghachi omume nke usoro abụọ (dịka usoro organic mmiri), dịka na mmeghachi omume nnọchi nucleophilic, nkwadebe hydrocarbon halogenated, etherification, na mmeghachi omume esterification, nke nwere ike ịbawanye mmepụta ma belata oge mmeghachi omume.

2. Elektrọkemistri
A na-eji ya eme ihe n'ihe gbasara imepụta batrị, dịka ihe mgbakwunye electrolyte, ọ nwere ike ime ka arụmọrụ electrochemical ka mma, ọkachasị na nyocha nke batrị lithium-ion, na-egosi ojiji nwere ike ime.
3. Mmepụta ọgwụ
Njirimara ya nke igbu nje bacteria na-eme ka ọ bụrụ ihe dị mkpa maka nkwadebe ọgwụ nje bacteria, ebe ọ na-akwalite usoro dị mkpa na mmepụta ọgwụ dịka ịmepụta carbon nitrogen na njikọ carbon oxygen.
4. Nchedo gburugburu ebe obibi
A na-etinye ya n'ọnọdụ ọgwụgwọ mmiri site na mmetụta mwepụta nwayọ nke ion ígwè dị arọ, maka iwepụ ma ọ bụ weghachite ihe ndị na-emerụ emerụ na mmiri.
5. Mmepụta kemịkalụ
A na-eji ya eme ihe n'ọhịa nke kemịkalụ dị mma maka imepụta agba, ihe na-esi ísì ụtọ, na ihe polymer, ma na-esonye na alkylation, acylation, na mmeghachi omume ndị ọzọ.
