Siv:
- 5-bromo-2,3-dichloropyridine yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis.
-Nws tuaj yeem siv los npaj cov ntawv sau npe uas muaj cov pa roj carbon monoxide carbon isotopes.
Txoj Kev Npaj:
Txoj kev npaj ntawm -5-bromo-2,3-dichloropyridine feem ntau yog tau los ntawm bromination hloov cov tshuaj tiv thaiv ntawm 2,3-dichloro-5-nitropyridine. Txoj kev tshwj xeeb yog thawj zaug ua rau 2,3-dichloro-5-nitropyridine nrog phosphorus trichloride, thiab tom qab ntawd ua cov tshuaj tiv thaiv bromination hloov nrog bromine.
Cov ntaub ntawv kev nyab xeeb:
- 5-bromo-2,3-dichloropyridine yog cov organic compound thiab yuav tsum ua raws li cov txheej txheem kev nyab xeeb thaum tuav thiab siv.
-Nws yuav ua rau lub qhov muag, tawv nqaij thiab ua pa, yog li hnav tsom iav, hnab looj tes thiab daim npog qhov ncauj.
-Thov khaws cia kom zoo, kom deb ntawm hluav taws, cua sov thiab oxidant, thiab tsis txhob sib cuag nrog cov kua qaub thiab alkali.
-Thaum nqus tau los yog tsis sib cuag, ntxuav qhov chaw raug mob tam sim ntawd thiab nrhiav kev pab kho mob.
