Isticmaalka
Trimethyl borate waa falgal waxtar leh oo ku jira isku-darka dabiiciga ah. Waxay ku lug leedahay soo saarista resins, waxes iyo rinjiyeyaal waxayna u dhaqantaa sidii wakiil methylation ah. Iyada oo ah isha boron, Trimethyl borate waxaa loo isticmaalaa in lagu diyaariyo waxyaabaha ka hortaga dabka, anti-oxidants iyo kuwa ka hortaga daxalka. Waxay la falgashaa reagents-ka Grignard oo ay ku xigto hydrolysis si loo diyaariyo boronic acid. Waxa kale oo loo isticmaalaa sidii hordhac u ah esters-ka borate, kaas oo ka hela falgalka isku-xidhka Suzuki. Waxaa loo isticmaalaa sidii gaas ogaane neutron ah marka uu joogo miiska scintillation; sida kor u qaadida falgallada diborane.
Trimethyl borate waxay la falgashaa Grignard reagent ama organolithium compounds si ay u soo saaraan dimethyl boronates, kuwaas oo marka daaweynta aashitada biyaha kadib ay bixiyaan asiidhyada boronic ee u dhigma. Asiidhyada boronic ama esters-ka ka dhasha ayaa ah dhexdhexaadin waxtar leh oo ku jira falgallo isku-xidhan oo kala duwan sida isku-xidhka Suzuki iyo isku-xidhka Chan-Lam. Waxa kale oo loo isticmaalaa diyaarinta sodium borohydride.
