Daim ntawv thov
1. 2-Bromobiphenyl feem ntau yog siv los ua ntau yam intermediate hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv cross-coupling cov tshuaj tiv thaiv (xws li, Suzuki, Stille) los ua ke ntau dua biaryl systems.
2. 2-Bromobiphenyl CAS 2052-07-5 ua lub tsev tseem ceeb rau cov tshuaj, agrochemicals, kua muaju, thiab cov khoom siv hluav taws xob organic.
3. Cov tshuaj no kuj tseem siv rau hauv kev tshawb fawb los tsim cov ligands, polymers, thiab ua tus qauv substrate hauv kev tshawb fawb txoj kev.
Cia thiab ceev faj
1. Khaws 2-bromobiphenyl nyob rau hauv ib qho chaw txias, qhuav, zoo-ventilated qhov chaw, tiv thaiv los ntawm lub teeb thiab deb ntawm tshav kub thiab ignition qhov chaw.
2. Khaws 2-Bromobiphenyl CAS 2052-07-5 lub thawv kaw kom nruj thiab sib cais los ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, thiab cov hlau reactive.
3. Kov nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav tiv thaiv, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus pa los yog hmoov av.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv tsim nyog ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv).
2. Sau 2-Bromobiphenyl CAS 2052-07-5 cov khoom spilled nrog cov cuab yeej huv si, tsis muaj teeb meem. Rau cov kua, nqus nrog cov khoom inert (xws li, xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv lub thawv ntim khoom pov tseg uas raug kaw.
3. Tiv thaiv qhov sib xyaw kom tsis txhob nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Ntxuav qhov chaw cuam tshuam nrog dej thiab xab npum.
Cov ntaub ntawv kev nyab xeeb
1. 2-Bromobiphenyl muaj teeb meem yog tias nqos, nqus tau, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij thiab qhov muag khaus thiab yuav ua rau ua pa puas.
2. 2-Bromobiphenyl CAS 2052-07-5 yog combustible thiab tej zaum yuav emit fumes lom (hydrogen bromide, carbon oxides) thaum tshav kub kom decomposition.
3. Nco ntsoov sab laj nrog 2-bromobiphenyl Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm.
