Daim ntawv thov
1. Ua raws li qhov nruab nrab tseem ceeb rau kev sib txuas ntawm benzofuran-raws li kws tshuaj tsom rau hyperprolinemia.
2. Pab 4-Bromo-2-fluorotoluene CAS 51436-99-8 ua lub tsev tseem ceeb rau kev tsim cov tshuaj agrochemicals xws li tshuaj tua kab thiab fungicides.
3. Muaj nuj nqi raws li ib tug reagent rau kev npaj hloov cov aromatic derivatives nyob rau hauv zoo organic synthesis.
Cia thiab ceev faj
1. Khaws rau hauv cov thawv ntim amber kaw ntawm 10–25℃hauv qhov chaw txias, zoo- qhov cua qhov chaw kom deb ntawm tshav kub thiab qhib nplaim taws.
2. Hnav 4-Bromo-2-fluorotoluene CAS 51436-99-8 hnab looj tes tiv thaiv kab mob, tsom iav kev nyab xeeb thiab lub tshuab ua pa kom tsis txhob nqus pa thiab tiv thaiv daim tawv nqaij.
3. Tiv thaiv kev sib xyaw nrog cov oxidants muaj zog thiab cov hlau ua haujlwm; pov tseg cov pov tseg ntawm cov ntawv tso cai muaj kev phom sij rau cov neeg ua haujlwm.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 4-Bromo-2-fluorotoluene?
1. Muaj cov reactive bromine thiab electron- rho tawm fluorine kom muaj txiaj ntsig zoo - coupling cov tshuaj tiv thaiv.
2. Txhim kho 4-Bromo-2-fluorotoluene CAS 51436-99-8 lub lipophilicity thiab stability ntawm lub hom phiaj kws tshuaj thiab agrochemical khoom.
3. Muab pov thawj zoo solubility nyob rau hauv uas tsis yog -protic organic solvents, kom ntseeg tau homogeneous cov tshuaj tiv thaiv systems.
Cov ntaub ntawv kev nyab xeeb
4-Bromo-2-fluorotoluene CAS 51436-99-8 muaj teeb meem yog tias nqos tau (H302) thiab khaus tawv nqaij (H315), qhov muag (H319) thiab kab mob ua pa (H335). Nws raug cais nyob rau hauv GHS07 yam phom sij, nrog rau UN thauj tus lej UN2810 rau kev xa khoom phom sij. Kev raug mob ntev yuav ua rau kiv taub hau, xeev siab lossis mob hauv zos; nws yog incompatible nrog muaj zog oxidants thiab txo cov neeg ua hauj, uas yuav ua rau exothermic tshua.
