Isticmaal:
- 3, pinacol ester acid waa mid ka mid ah dhexdhexaadiyeyaasha muhiimka ah ee isku dhafka dabiiciga ah. Waxaa loo isticmaali karaa sidii reagent dhismaha C-O iyo C-C bonds, waxaana badanaa loo isticmaalaa kicinta falcelinta isku-xidhka C-C sida falcelinta Suzuki iyo falcelinta Stille.
- Xarunta waxaa sidoo kale loo isticmaali karaa in lagu diyaariyo kooxo kale oo shaqeynaya ama xeryahooda, sida aldehyde, ketones iyo acids.
Habka:
- 3, aashitada pinacol ester guud ahaan waxaa loo diyaariyey iyadoo lagu falcelinayo Pyran leh boronic acid pinacol oo hoos yimaada catalysis alkali. Habka diyaarinta gaarka ah waxaa lagu dooran karaa iyadoo loo eegayo shuruudaha dhabta ah, iyo habka diyaarinta caadiga ah waxaa ka mid ah isticmaalka sodium borate iyo pinacol si ay uga falceliyaan xaaladaha alkaline.
Macluumaadka Badbaadada:
3, aashitada pinacol ester waxay waxyeelo u keeni kartaa caafimaadka iyo deegaanka. Isticmaalku waa in uu raacaa hababka shaybaadhka ee saxda ah oo lagu qalabeeyaa qalabka ilaalinta shakhsi ahaaneed ee lagama maarmaanka ah, sida galoofyada shaybaadhka iyo ilaalinta indhaha.
Intaa waxaa dheer, macluumaadka badbaadada gaarka ah iyo tilmaamaha hawlgalka waa inay tixraacaan xaashida xogta badbaadada xarunta (SDS) ama tixraac kale oo kiimiko ah oo la isku halayn karo.
