Cia thiab ceev faj
Khaws 2-Bromo-9 9-dimethylfluorene CAS 28320-31-2 (dawb crystalline hmoov, mp 68 degree, ceev 1.346g/cm³, bp 190℃/ 2mmHg, purity Ntau dua los yog sib npaug rau 5% ntawm qhov sib npaug rau 98% iav / HDPE nruas nyob rau hauv ib qho chaw txias, qhuav, tsaus nti & zoo-ventilated cheeb tsam, deb ntawm qhib hluav taws, muaj zog oxidants thiab ncaj qha tshav ntuj. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; zam plua plav nqus, tawv nqaij/qhov muag thiab noj kom tsis txhob mob me me. Reseal nruj nreem tom qab siv; pov tseg cov khoom pov tseg hauv ib cheeb tsam fluorene nplua tshuaj ib puag ncig cov cai (tsis txhob tso dej).
Dab tsi yog qhov txiaj ntsig ntawm kev noj 2-Bromo-9 9-dimethylfluorene?
2-Bromo{1}}dimethylfluorene CAS 28320-31-2yog ib qho kev lag luam brominated fluorene heterocyclic intermediate nrog dej toxicity, nruj me ntsis txwv tsis pub tso rau hauv dej thiab ncaj qha ntshiab- tsim kev sib cuag tib neeg; Cov plua plav uas tsis muaj hmoov av tuaj yeem ua rau ua pa me me / khaus tawv nqaij, thiab nws muaj sijhawm ntev - cuam tshuam rau cov kab mob hauv dej.
Hauv kev tswj hwm kev siv, 2-Bromo-9 9-dimethylfluorene CAS 28320-31-2 nta siab bromine hloov purity thiab zoo heev cross-coupling reactivity, zoo solubility nyob rau hauv cov kuab tshuaj organic, ruaj khov zog nyob rau hauv kaw tsaus nti cia, thiab 9,9-dimethyl qauv txhim khu cov khoom siv thermal stability thiab steric hindrance.
