Xwm:
-Cov tsos mob: cov kua tsis muaj xim
- Melting point: -24 ℃
- Kub taw tes: 98-100 ℃
Qhov ceev: 1.65g / cm3
-Solubility: Soluble nyob rau hauv organic solvents xws li cawv thiab ethers
Siv:
2-Chloro-5-fluorobenzyl bromide tuaj yeem siv rau hauv cov organic synthesis cov tshuaj tiv thaiv, yog ib hom alkylation reagent thiab halogen reagent. Nws yog feem ntau siv nyob rau hauv kev npaj ntawm aromatic ether tebchaw, tshuaj thiab tshuaj tua kab intermediates.
Txoj Kev Npaj:
2-Chloro-5-fluorobenzyl bromide tuaj yeem npaj los ntawm cov kauj ruam hauv qab no:
- Ua ntej, 2-chloro-5-fluorobenzene reacted nrog sodium bromate kom tau 2-chloro-5-fluorobenzoic acid.
-Tom qab ntawd hnov 2-chloro-5-fluorobenzoic acid nrog brominated sulfoxide kom tau 2-chloro-5-fluorobenzoic acid sulfoxide.
-Thaum kawg, 2-chloro-5-fluorobenzoic acid sulfoxide ester yog reacted nrog thionyl chloride kom tau 2-Chloro-5-fluorobenzyl bromide.
Cov ntaub ntawv kev nyab xeeb:
2-Chloro-5-fluorobenzyl bromide yog cov organic bromine compound thiab yuav tsum tau ua raws li kev soj ntsuam kev nyab xeeb. Nws yog khaus thiab lom thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab ua pa ib ntsuj av. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav kev nyab xeeb thiab daim npog ntsej muag yuav tsum hnav thaum ua haujlwm.
