Daim ntawv thov
① Kev Ua Haujlwm 4-Biphenylboronic acid ua ib qho tseem ceeb reagent rau Suzuki-Miyaura cross-coupling cov tshuaj tiv thaiv, ua kom muaj kev sib txuas ntawm biaryl kws tshuaj, kua siv lead ua kua thiab OLED cov ntaub ntawv los ntawm kev sib txuas nrog aryl halides los tsim cov khoom sib xyaw ua ke.
② Pab 4-Biphenylboronic acid CAS 5122-94-1 ua ib qho tseem ceeb nruab nrab rau kev npaj cov organic dyes thiab pigments ntawm boronic acid - kho coupling los kho chromophore lug thiab txhim khu xim stability.
③ Kev ua haujlwm raws li lub tsev thaiv rau cov organic semiconductors thiab cov khoom ntxeem tau, txhawb R & D ntawm siab - kev ua haujlwm hluav taws xob thiab cov khoom siv adsorption nrog nws cov tawv biphenyl - boronic acid qauv.
Cia thiab ceev faj
Khaws 4-Biphenylboronic acid CAS 5122-94-1 ntawm 2-8℃nyob rau hauv kaw amber iav / HDPE nruas nyob rau hauv ib tug txias, qhuav, tsaus nti zoo-ventilated cheeb tsam, deb ntawm qhib hluav taws, muaj zog oxidants, muaj zog bases thiab ncaj qha tshav ntuj. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; zam kev nqus pa, daim tawv nqaij / qhov muag sib cuag & noj kom tsis txhob mob me me. Rov ua kom nruj tom qab siv kom tsis txhob nqus dej noo, hydrolysis thiab dimerization rau anhydride. Pov tseg los ntawm cov ntawv tso cai pov tseg pov tseg; thauj khoom raws li tsis muaj kev phom sij, khaws cia hauv tub yees, tsis txhob muaj qhov kub thiab txias thiab sib xyaw nrog halides / muaj zog hauv paus.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 4-Biphenylboronic acid?
4-Biphenylboronic acid CAS 5122-94-1 yog qis - tshuaj lom dawb crystalline khoom nrog tshuaj lom neeg ruaj khov zoo heev, tsis yog - flammable, tsis tshua muaj hygroscopicity thiab tsis muaj kev pheej hmoo ntawm tus kheej-polymerization nyob rau hauv kev cia. boronic acid pab pawg muaj kev sib txuas ua haujlwm siab; rigid biphenyl core ua kom muaj kev ruaj ntseg ntawm cov khoom lag luam, siab purity guarantees siab cov tshuaj tiv thaiv tawm los thiab xaiv, zoo solubility nyob rau hauv THF / DMF / ethanol, nqi - zoo rau loj - scale synthesis nrog ruaj khov batch zoo thiab yooj yim purification.
