Ilaalinta Ilaalinta TFA 99.7%

Gaar ahaan: 250kg / durbaan

Trifluoroacetic acid, oo loo soo gaabiyo TFA sidoo kalena loo yaqaano perfluoroacetic acid, waa dareere aan midab lahayn, qiiqaya, aad u daxalaysan oo leh ur xajiin leh, ur xajiimo leh. Badeecadeena nadiifka sare ah waxay ku guulaysataa 99.7% nadiif ah, iyada oo bixisa waxqabad aan caadi ahayn oo loogu talagalay isku dhafka peptide, falcelinta ka hortagga organic, soo saarista daawooyinka, iyo codsiyada catalytic ee gaarka ah ee u baahan acidity ultra-awood leh.

Sida karboksylic acid ee ugu fudud, trifluoroacetic acid waxay leedahay sifooyin kiimiko oo gaar ah oo ka sooca dhammaan asiidhyada kale ee organic. Saddexda atom ee fluorine ee aadka u sarreeya ee ku xidhan kooxda methyl waxay abuuraan saamayn soo jiidasho leh oo elektaroonig ah oo aan caadi ahayn, taasoo keentay pKa qiyaastii 0.3 — taasoo TFA ka dhigaysa mid ka mid ah asiidhyada organic ugu xooggan ee la yaqaan. Aysiidhkan xad dhaafka ah, oo ay weheliso nucleophilicity hoose, isbeddel sare (barka karkarinta 72°C), iyo milanka aadka u wanaagsan ee dareerayaasha organic, waxay awood u siinaysaa xakamaynta saxda ah ee falcelinta aashitada-catalyzed iyo fududaynta ka saarida isku-dhafka falcelinta.

Goobta peptide iyo borotiinka kiimikada waxay ka dhigan tahay codsiga ugu muhiimsan ee TFA, halkaas oo ay u adeegto sida reagent-ka caadiga ah ee ka nadiifinta peptides-ka isku-dhafan ee haraaga adag ee wejiga adag iyo ka saarida kooxaha ilaalinta aashitada. Heerka Fmoc (fluorenylmethyloxycarbonyl) borotokoollada isku-dhafka peptide-ada adag, TFA cocktails oo ay ku jiraan wax-qashin-qaadayaashu waxay si hufan u difaacaan kooxaha ilaalinta silsiladda dhinac-dhinacyada iyagoo ka siidaaya peptide-ka dhammaystiran ee taageerada resin. Darajada nadiifka sare waxay hubisaa oksaydhka ugu yar iyo falcelinta dhinaca trifluoroacetylation ee wax u dhimi karta daacadnimada peptide iyo dhaqdhaqaaqa noolaha.

Soo saarista dawooyinka, TFA waxay u shaqeysaa sidii reagen la isku beddeli karo oo ka-talisa fal-celinta esterifications, transesterifications, iyo falcelinta dib-u-habaynta ee xaaladaha khafiifka ah. Xaruntu waxay u adeegtaa sidii wakiilka isku-xidhka ion-ka ah ee chromatography dareeraha waxqabadka-sare ee wejiga-kale (HPLC), hagaajinta xallinta ugu sarreysa xeryahooda dawooyinka aasaasiga ah. Codsiyada dheeraadka ah waxaa ka mid ah isticmaalka sida dareere loogu talagalay NMR spectroscopy, reagent soo saarista trifluoroacetate esters iyo anhydrides, iyo kicinta Friedel-Crafts acylations iyo aldol condensations.

Our 99.7% trifluoroacetic acid saafi ah waxay la kulmaa qeexitaanno adag oo loogu talagalay maadada hoose ee biyaha, wasakhowga ugu yar ee hydrogen fluoride, iyo la xakameeyey hadhaaga aan kacsanayn, hubinta waxqabadka lagu kalsoonaan karo ee shaybaarada isku dhafka peptide, soosaarayaasha dawooyinka, iyo machadyada cilmi-baarista ee u baahan ultra-awood, nadiifin sare oo nadiif ah oo lagu dalbado aashitada perfluorinated ee loo baahan yahay.

Shirkaddayadu waxay si qoto dheer ugu hawlan tahay warshadaha kiimikada waxayna inta badan wax ka qabataa noocyo kala duwan oo alaabta ceeriin kiimikaad ah sida surfactants, kiimikooyinka ganaaxa ee saliidda, alaabta ceeriin ee aasaasiga ah, dareerayaasha organic, dhexdhexaadinta dawooyinka iyo sunta cayayaanka, wakiilada daaweynta biyaha, iyo cuntada lagu daro. Alaabooyinkeeda ayaa si weyn looga isticmaalaa warshado kala duwan.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
