Nws cov khoom tseem ceeb yog raws li nram no:
-Cov tsos mob: tsis muaj xim rau lub teeb daj siv lead ua
- melting point: 43-46 ℃
-Boiling point: 209-210 ℃
-Solubility: me ntsis soluble hauv dej, soluble hauv cov organic solvents xws li ethanol, dimethylformamide
5-Bromo-2-chlorostyridine muaj ntau yam kev siv hauv cov organic synthesis, thiab feem ntau yog siv rau hauv kev npaj ntawm pyridine derivatives, xws li tshuaj thiab tshuaj tua kab. Nws tseem tuaj yeem siv los ua ligand rau kev sib txuas ntawm organometallic complexes.
Hauv txoj kev npaj, 5-Bromo-2-chloropyridine tuaj yeem tau txais los ntawm kev ntxiv chlorination rau 2-bromopyridine kom tau txais kev hloov pauv. Cov kev mob tshwm sim tshwj xeeb yuav raug hloov kho raws li qhov kev sim xav tau.
Hais txog kev nyab xeeb cov ntaub ntawv, 5-Bromo-2-choropyridine yog khaus thiab rhiab heev thiab tej zaum yuav muaj teeb meem rau lub qhov muag, tawv nqaij, ua pa thiab digestive system. Ua tib zoo saib xyuas kev tiv thaiv thaum siv thiab tuav, suav nrog hnav tsom iav tiv thaiv, hnab looj tes thiab daim npog qhov ncauj. Nyob rau tib lub sijhawm, nws yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated, deb ntawm qhov hluav taws kub thiab cua sov.
