Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 nke a makwaara dị ka sodium triacetoxyhydroborate, nke a na-akpọkarị STAB, bụ ihe mejupụtara kemịkalụ nwere usoro Na(CH3COO)3BH. Dịka borohydrides ndị ọzọ, a na-eji ya dị ka ihe na-ebelata ihe na mmepụta organic. A na-akwadebe nnu a na-enweghị agba site na protonolysis nke sodium borohydride na acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Agbanyeghị, n'adịghị ka sodium cyanoborohydride, triacetoxyborohydride na-enwe mmetụta mmiri, a pụghịkwa iji mmiri mee ihe dị ka ihe mgbaze na ihe a na-eme ka ọ dịghachi ndụ, ọ dịghịkwa ekwekọ na methanol. Ọ na-emeghachi omume naanị nwayọ na ethanol na isopropanol ma enwere ike iji ya na ndị a. Enwere ike iji NaBH(OAc)3 mee ihe maka mbelata alkylation nke amine abụọ yana adducts aldehyde-bisulfite.
