3. Muaj 1-Bromo-2 4-difluorobenzene zoo solubility nyob rau hauv cov organic solvents xws li toluene thiab dichloromethane, yoog mus rau ntau yam organic tshuaj tiv thaiv systems.
4. Muab 2 4-Difluorobromobenzene CAS 348-57-2 siab tshuaj purity thiab ruaj khov reactivity, haum rau ob qho tib si kuaj - scale tshawb fawb thiab industrial - scale ntau lawm.
Cov ntaub ntawv kev nyab xeeb
1-Bromo-2 4-difluorobenzene yog hom 3 flammable kua (UN 1993, Packing Group III) nrog rau cov kua flammable thiab vapor (H226). Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319) thiab khaus khaus khaus khaus (H335) thaum tiv tauj los yog nqus tau pa . 2 4-Difluorobromobenzene CAS 348-57-2 yog incompatible nrog muaj zog acids, bases thiab oxidants; Kev sib xyaw tsis raug tuaj yeem ua rau decomposition thiab tso tawm cov pa phem hydrogen fluoride. Kev sib cuag ntawm daim tawv nqaij ntev tuaj yeem ua rau muaj tshuaj lom neeg kub hnyiab, thiab kev nqus pa siab tuaj yeem ua rau ua pa tsis xis nyob.
