Pentafluorophenol CAS 771-61-9
Pentafluorophenol wani fili ne mai ƙyalƙyali mai ƙyalƙyali mai ƙyalli tare da ƙarancin tsangwama, wanda shine muhimmin tsaka-tsaki don shirya kayan kristal mai ƙarfi mai ƙarfi. Ya dace musamman don shirye-shiryen kayan kristal mai ƙyalƙyali da yawa. Lokacin haɗe da ƙananan danko da babban dielectric anisotropy nematic ruwa crystal kayan, Multi fluorinated monomer ruwa crystal kayan na iya ƙara da dipole nisa na kwayoyin, rage mayar da martani lokaci, inganta gani Properties na ruwa crystal kayan, da kuma inganta tsabta.

Pentafluorophenol wani muhimmin tsaka-tsaki ne wanda aka fi amfani dashi a cikin shirye-shiryen magunguna, crystal na ruwa, da tsaka-tsakin kayan polymer. Misali, a fagen magani da magungunan kashe qwari, ana amfani da pentafluorophenol sau da yawa don shirya esters mai aiki na pentafluorophenyl don haɗakar peptide, ta haka ne ke haɓaka samuwar peptide bond. Pentafluorophenol esters za a iya amfani da m-lokaci kira na peptides, ruwa-lokaci kira, kazalika don kare amino acid alkyl esters ko sulfonic acid kungiyoyin.
Yawancin lokaci cushe a 25kg / drum, kuma kuma za a iya yi musamman kunshin.
