Ntchito:

N,N,N',N'-Tetramethylchloroformamidinium Hexafluorophosphate (TCFH) (CAS: 94790-35-9), coupling reagent for peptide synthesis ndi poyambira zinthu pokonzekera zolumikizira zina.TCFH ndi yabwino yopanda hygroscopic peptide synthesis coupling reagent.Monga ambiri kutsegula reagent wa olimba gawo umagwirira, TCFH makamaka amalimbikitsa mapangidwe carboxylic asidi amine zotumphukira osati amide mu lumikiza ndondomeko amino zidulo.Ndizothandiza kwambiri pakuphatikiza ma amino acid omwe amalepheretsa kwambiri, ndipo ali ndi mawonekedwe osavuta komanso osavuta kaphatikizidwe komanso moyo wautali.
TCFH ndi yotetezeka, yotsika mtengo ya ester komanso kaphatikizidwe kake ka amide.
TCFH monga reagent ili ndi maubwino angapo kuphatikiza pachuma:
- Chifukwa champhamvu yolumikizirana, itha kugwiritsidwa ntchito pazomwe zidachitika kale pogwiritsa ntchito ma carbodiimide-mediated couplings, kupitilira motere ntchito yake yopanga ma esters, diacyl amides ndi acylation of non-reactive amines.
- Ndi yolimba, yosasunthika bwino, ikasungidwa mozungulira 0°C
- Pogwiritsa ntchito zowonjezera zomwe zimapezeka pophatikizana, katswiri wamankhwala amatha kupeza chiŵerengero choyenera cha reagent kuti chikhale bwino pakati pa zokolola za mankhwala ndi zomwe zimachitika pambali kuphatikizapo epimerization.
