Sodium triacetoxyborohydride (STAB) CAS 56553-60-7 sidoo kale loo yaqaan sodium triacetoxyhydroborate, oo sida badan loo soo gaabiyo STAB, waa iskudhis kiimiko ah oo leh caanaha Na (CH3COO) 3BH. Sida borohydrides kale, waxaa loo isticmaalaa sidii wakiilka yaraynta ee isku-dhafka organic. Cusbadaan aan midabka lahayn waxaa lagu diyaariyaa protonolysis of sodium borohydride oo leh acetic acid: NaBH4 + 3 HO2CCH3 → NaBH(O2CCH3)3 + 3 H2.

Iyadoo ay ugu wacan tahay saamaynta istiraatijiga ah iyo elektiroonigga ah ee kooxaha acetoxy, sodium triacetoxyborohydride waa wakiil yaraynta khafiifka ah marka loo eego sodium borohydride ama xitaa sodium cyanoborohydride. Intaa waxaa dheer, NaBH (OAc) 3 waxay ka fogaataa alaabada dhinaca sunta ah ee ay dhaliso sodium cyanoborohydride. Sodium triacetoxyborohydride waxay si gaar ah ugu habboon tahay dib-u-dhiska aldehyde iyo ketones.
Si kastaba ha ahaatee, si ka duwan sodium cyanoborohydride, triacetoxyborohydride waa biyo-xasaasi ah, biyahana looma isticmaali karo sida dareere leh reagent-kan, mana la jaan qaadi karo methanol. Waxay si tartiib tartiib ah ula falgashaa ethanol iyo isopropanol waxaana loo isticmaali karaa kuwan. NaBH (OAc) 3 waxa kale oo loo isticmaali karaa alkylation-ka yaraynta aminyada sare ee aldehyde-bisulfite.
