Pentafluorophenol CAS 771-61-9
Pentafluorophenol waa isku-dhismeed dareere ah oo fluorinated badan leh oo leh caqabad hooseeya, taas oo dhexdhexaad muhiim ah u ah diyaarinta walxaha crystal dareeraha ah ee waxqabadka sarreeya. Waxay si gaar ah ugu habboon tahay diyaarinta walxaha crystal dareere monomer fluorinated multi. Marka lagu qaso viscosity hoose iyo dielectric anisotropy nematic dareere dareere ah walxaha crystal, multi fluorinated monomer dareere ah walxaha waxay kordhin karaan masaafada dipole ee molecules, yareeyaan waqtiga jawaabta, hagaajinta sifooyinka muuqaalka ah ee alaabta crystal dareere, iyo kor u caddayn.

Pentafluorophenol waa dhex dhexaad muhiim ah oo inta badan loo isticmaalo diyaarinta dawooyinka, crystal dareere, iyo dhexdhexaadiyaha walxaha polymer. Tusaale ahaan, dhinacyada daawada iyo sunta cayayaanka, pentafluorophenol waxaa badanaa loo isticmaalaa in lagu diyaariyo pentafluorophenyl esters firfircoon ee peptide synthesis, taas oo kor u qaadeysa sameynta bonds peptide. Esters Pentafluorophenol waxaa loo isticmaali karaa isku-darka adag ee peptides-ka, isku-dhafka dareeraha-wejiga, iyo sidoo kale ilaalinta amino acid alkyl esters ama kooxaha sulfonic acid.
Caadi ahaan waxaa lagu buuxiyaa 25kg/durbaan, sidoo kale waxaa la samayn karaa xirmo habaysan.
