Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 e tsejoang hape e le sodium triacetoxyhydroborate, e atisang ho khutsufatsoa STAB, ke motsoako oa lik'hemik'hale o nang le foromo ea Na(CH3COO)3BH. Joalo ka li-borohydride tse ling, e sebelisoa e le moemeli oa ho fokotsa motsoako oa lintho tse phelang. Letsoai lena le se nang 'mala le lokisoa ka protonolysis ea sodium borohydride ka asiti ea acetic: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Leha ho le jwalo, ho fapana le sodium cyanoborohydride, triacetoxyborohydride e angwa ke metsi, mme metsi a ke ke a sebediswa e le solvent ka reagent ena, mme ha e tsamaisane le methanol. E arabela butle feela ka ethanol le isopropanol mme e ka sebediswa le tsena. NaBH(OAc)3 e ka boela ya sebediswa bakeng sa alkylation e fokotsang di-amine tsa bobedi ka di-adduct tsa aldehyde-bisulfite.
Ka kopo ikopanye le rona ho fumana COA le MSDS. Kea leboha.
