Cov ntaub ntawv kev nyab xeeb
Cov tshuaj no yog cais raws li Class 3 flammable kua (H226), thiab nws cov vapors tuaj yeem tsim cov khoom tawg nrog huab cua. Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319) thiab khaus khaus ua pa (H335) thaum tiv tauj lossis nqus tau pa . 3 4-difluorobromobenzene CAS 348-61-8 yog incompatible nrog muaj zog hauv paus, acids 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 nyuaj.
