Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 oo sidoo kale loo yaqaan sodium triacetoxyhydroborate, oo si caadi ah loo soo gaabiyo STAB, waa isku-dhis kiimiko ah oo leh qaacidada Na(CH3COO)3BH. Sida borohydrides-yada kale, waxaa loo isticmaalaa sidii wakiil yareeya isku-darka dabiiciga ah. Cusbadaan aan midab lahayn waxaa lagu diyaariyaa protonolysis-ka sodium borohydride oo leh aashitada acetic: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.
Si kastaba ha ahaatee, si ka duwan sodium cyanoborohydride, triacetoxyborohydride waa mid xasaasi u ah biyaha, biyahana looma isticmaali karo sidii dareere ahaan oo leh falgalkan, mana la jaanqaadi karo methanol. Waxay si tartiib tartiib ah ula falgashaa ethanol iyo isopropanol waxaana loo isticmaali karaa kuwan. NaBH(OAc)3 waxaa sidoo kale loo isticmaali karaa alkylation-ka yareeya ee amines-ka labaad oo leh aldehyde-bisulfite adducts.
