Hexafluoroisopropyl methyl ether (HFIPME) waa dhisme ether ah oo kacsan oo kiimiko ahaan deggan kaas oo leh codsiyo kala duwan oo dhinacyo kala duwan ah.Waxaa caadi ahaan loo isticmaalaa sida dareere, reagent, iyo wakiilka ilaalinta sababtuna tahay sifooyinkeeda gaarka ah.Mid ka mid ah isticmaalka aasaasiga ah ee HFIPME waa sida dareere ah warshadaha dawooyinka iyo kiimikada.Milicsigeeda aadka u fiican ee isku-dhafka dabiiciga ah iyo kuwa aan noolaha ahayn labadaba waxay ka dhigaysaa doorasho ku habboon in lagu kala diro walxo kala duwan.HFIPME waxay si gaar ah faa'iido u leedahay in la milo xeryahooda fluoriined aadka u sarreeya, peptides, iyo polymers gaar ah.Awooddeeda ay ku milmi karto walxahan adag waxay ka dhigaysaa mid qiimo leh helitaanka daroogada, kimistariga daawada, iyo isku dhafka polymer. Marka lagu daro astaamaha dareeraha, HFIPME waxay u shaqayn kartaa sidii reagent falcelinta qaarkood.Tusaale ahaan, waxaa loo isticmaali karaa in kor loogu qaado falcelinta fuuq-baxa iyadoo laga saarayo biyaha isku-darka falcelinta.HFIPME waxa kale oo ay awood u leedahay in ay u dhaqanto sidii aashitada Lewis khafiifka ah, fududaynta falcelino kala duwan sida Friedel-Crafts acylation iyo falcelinta baaskiilka.Dareen-celinteeda iyo doorashadu waxay ka dhigaysaa reagent la mid ah isku-dhafka organic. Intaa waxa dheer, HFIPME waxay caan ku tahay awoodda ay u leedahay inay dejiso xeryahooda labile.Waxay u dhaqmi kartaa sidii wakiil difaac ah si looga hortago hoos u dhaca ama oksaydhka walxaha xasaasiga ah inta lagu jiro kaydinta ama hababka falcelinta.Tani waxay si gaar ah muhiim ugu tahay xasilinta dhexdhexaadiyeyaasha falceliska ah, ilaalinta kooxaha shaqeeya, iyo ilaalinta hufnaanta molecules jilicsan.Guryaha xasilinta ee HFIPME waxay ka dhigaan mid qiimo leh dhinacyada dawooyinka, kiimikooyinka beeraha, iyo sayniska agabka.Iyadoo ay ugu wacan tahay barta karkarinta hoose (-24.7 °C), waxaa loo isticmaali karaa falcelinta heerkulka hoose iyo hababka.Dabeecadda HFIPME ee cryogenic waxay awood u siinaysaa in laga shaqeeyo goobaha sida cryobiology, cryo-electron microscopy, iyo cilmi-baarista superconductivity. Intaa waxaa dheer, HFIPME waxay muujisay karti-xirfadeedka falanqaynta kiimikada, gaar ahaan nukliyeerka magnetic resonance (NMR) spectroscopy.Sida dareere ah, waxay leedahay tirinta proton hoose, viscosity hoose, iyo sifooyin milmayn heer sare ah, taasoo ka dhigaysa doorasho ku habboon falanqaynta NMR.HFIPME ayaa inta badan door bida in la barto muunado adag, oo ay ku jiraan peptides, borotiinada, iyo alaabta dabiiciga ah.Guud ahaan, hexafluoroisopropyl methyl ether (HFIPME) waa isku-dhafan kala duwan oo kala duwan oo la isticmaalo.Guryaha dareeraha ah, falcelinta, saamaynta xasilinta, dabeecadda cryogenic, iyo waafaqid falanqaynta NMR waxay ka dhigaysaa mid qiimo leh codsiyada sayniska iyo warshadaha ee kala duwan.Laga soo bilaabo isku-darka dawooyinka ilaa cryobiology, HFIPME waxay door muhiim ah ka ciyaartaa dhinacyo badan.
