Daim ntawv thov
1. 4-(Trifluoromethoxy) benzyl bromide feem ntau yog siv los ua ntau yam alkylating tus neeg sawv cev thiab lub tsev thaiv hauv cov organic synthesis.
2. 4-(Trifluoromethoxy)benzyl bromide CAS 50824-05-0 yog ib qho tseem ceeb nruab nrab rau kev qhia 4-(trifluoromethoxy) benzyl pawg rau hauv cov tshuaj, agrochemicals, thiab cov ntaub ntawv.
3. Cov tshuaj no kuj tseem siv rau hauv kev sib txuas ntawm ligands, kua muaju, thiab lwm yam molecules ua haujlwm.
Cia thiab ceev faj
1. Khaws 4-(trifluoromethoxy) benzyl bromide nyob rau hauv ib lub thawv kaw nruj nreem rau hauv qhov chaw txias, qhuav, qhov cua zoo, tiv thaiv lub teeb thiab noo noo. Lub tub yees yuav raug pom zoo.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov neeg ua haujlwm oxidizing muaj zog, cov hauv paus muaj zog, thiab cov neeg ua haujlwm txo qis. **Moisture-sensitive; reacts nrog dej tso tawm corrosive hydrogen bromide.**
3. Kov 4-(Trifluoromethoxy) benzyl bromide CAS 50824-05-0 nrog ceev faj heev siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab lub tsho tiv no. Ib txwm siv lub fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw, xyuas kom muaj cua, thiab hnav cov iav tiv thaiv tag nrho (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa).
2. **Tsis txhob siv dej.** Ua tib zoo nqus cov kua nrog ib qho inert, qhuav, tsis yog -cov khoom siv hluav taws xob (xws li, xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, sau tias muaj kev phom sij.
3. Tiv thaiv 4-(Trifluoromethoxy)benzyl bromide CAS 50824-05-0 los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontaminate nto nrog ib tug haum non-aqueous hnyav, ua raws li tag nrho cov kev cai. Neutralize residual acid yog tias tsim nyog.
Cov ntaub ntawv kev nyab xeeb
1. 4-(Trifluoromethoxy) benzyl bromide yog ** corrosive thiab teeb meem **. Nws ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab ua pa ua pa. Nws yog noo noo-sensitive thiab reacts nrog dej los tsim hydrogen bromide gas.
2. 4-(Trifluoromethoxy) benzyl bromide CAS 50824-05-0 yog combustible thiab yuav emit heev lom thiab corrosive fumes (hydrogen bromide, carbonyl bromide, hydrogen fluoride, carbon oxides) thaum tshav kub kom decomposition los yog nyob rau hauv hluav taws.
3. Nco ntsoov sab laj nrog tus nom 4-(trifluoromethoxy) benzyl bromide Safety Data Sheet (SDS) thiab tuav nws raws li tus neeg sawv cev corrosive, noo noo-rhiab heev, thiab tshuaj lom alkylating tus neeg sawv cev. Cov txheej txheem tuav tshwj xeeb yuav tsum tau ua.
