Ojiji
Trimethyl borate bụ ihe na-enye aka n'ịmepụta ihe ndị sitere n'okike. Ọ na-etinye aka na mmepụta nke resins, waxes na agba ma na-arụ ọrụ dị ka ihe na-eme ka methylation dị. Dịka isi iyi boron, a na-eji Trimethyl borate akwadebe ihe ndị na-egbochi ire ọkụ, ihe ndị na-egbochi oxidants na ihe ndị na-egbochi corrosion. Ọ na-emeghachi omume na ihe ndị na-eme ka Grignard reagents na-esochi ya, wee jiri hydrolysis kwadebe boronic acid. A na-ejikwa ya dị ka ihe na-ebute ụzọ nke borate esters, nke na-achọta itinye ya na mmeghachi omume njikọ Suzuki. A na-eji ya dị ka gas nchọpụta neutron n'ihu ihe na-eme ka a na-akpọ scintillation counter; dị ka ihe na-akwalite mmeghachi omume diborane.
Trimethyl borate na-emeghachi omume na ihe na-eme ka Grignard reagent ma ọ bụ organolithium dị iche iche wee mepụta dimethyl boronates, nke mgbe a gwọchara acid mmiri, ha na-enweta boronic acid ndị kwekọrọ na ya. Boric acid ma ọ bụ esters ndị a na-enweta bụ ihe bara uru na mmeghachi omume dị iche iche dịka njikọ Suzuki na njikọta Chan-Lam. A na-ejikwa ya eme ihe na nkwadebe nke sodium borohydride.
