Taw qhia
2-chloro-5-fluoronicotinic acid. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 2-chloro-5-fluoronicotinic acid:
Zoo:
- 2-Chloro-5-fluoronicotinic acid yog cov xim tsis muaj kob crystalline.
- Nyob rau hauv chav tsev kub, nws muaj tsawg solubility thiab solubility tsawg nyob rau hauv dej.
- Nws muaj zog acidic thiab tuaj yeem hnov mob nrog alkali los tsim cov ntsev sib xws.
- 2-Chloro-5-fluoronicotinic acid yog cov khoom oxidizing heev.
Siv:
- 2-Chloro-5-fluoronicotinic acid tuaj yeem siv los ua cov reagent rau cov kua qaub muaj zog ua cov kua qaub catalyst hauv cov organic synthesis tshuaj.
- Nws tuaj yeem siv rau cov tshuaj fluorinated hauv cov organic synthesis, xws li fluorination thiab aromatic cyclofluorination.
- 2-Chloro-5-fluoronicotinic acid kuj tseem siv tau los ua ib qho nruab nrab hauv cov dyes thiab fluorescent brighteners.
Txoj kev:
- Ib txoj kev npaj rau 2-chloro-5-fluoronicotinic acid yog reacting 2,5-diaminoalkynyl niacin nrog ib tug tsim nyog tus nqi ntawm hydrofluoric acid thiab chlorinating agents.
Cov ntaub ntawv kev nyab xeeb:
- 2-chloro-5-fluoronicotinic acid yog cov organic compound uas ua rau khaus thiab tej zaum yuav muaj teeb meem rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Hnav cov iav tiv thaiv kom tsim nyog thaum siv thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
- Thaum lub sijhawm ua haujlwm, qhov cua yuav tsum tau ntxiv dag zog kom tsis txhob nqus cov pa tawm ntawm qhov sib xyaw no.
- 2-Chloro-5-fluoronicotinic acid yuav tsum tau khaws cia kom deb ntawm qhov chaw tshav kub thiab cov khoom siv hluav taws xob thiab khaws cia rau hauv qhov chaw qhuav, txias.
