Nhanganyaya
2-Fluoro-5-nitropyridine (2-Fluoro-5-nitropyridine) inonzi organic compound ine kemikari formula C5H3FN2O2. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: 2-Fluoro-5-nitropyridine ichena kune yakachenuruka yero yakasimba.
-Solubility: Inogona kunyungudutswa mune dzakawanda organic solvents, senge ethanol, dimethylformamide uye dichloromethane.
-Kunyungudika: Nzvimbo yekunyunguduka kwayo inenge 78-81 degrees Celsius.
Shandisa:
- 2-Fluoro-5-nitropyridine inobudirira organic synthesis yepakati, iyo yakakosha kushandiswa mukugadzirwa kwemishonga nemishonga yezvipembenene.
-Inogona kushandiswa kugadzira zvakasiyana-siyana biologically inoshanda makomisheni, akadai semishonga, dhayi uye machira.
Kugadzirira nzira:
- 2-Fluoro-5-nitropyridine inowanzogadzirirwa ne fluorination uye nitration ye pyridine.
-Iyo nzira yekugadzirira chaiyo inogona kunge ichiita pyridine nehydrogen fluoride kana ammonium fluoride kuti iwane 2-fluoropyridine. Iyo 2-fluoropyridine inobva yaitwa ne nitric acid kuti ipe 2-Fluoro-5-nitropyridine.
Zvekuchengetedza
- 2-Fluoro-5-nitropyridine isanganiswa yehupenyu ine imwe chiyero chengozi. Mukuita basa, zvinofanirwa kutevedzera zvinoenderana nemirairo yekuchengetedza kuchengetedza.
-Zvinogona kutsamwisa ganda nemeso, saka matanho ekudzivirira anofanira kutorwa kana akafumurwa, sekupfeka magirovhosi ekudzivirira uye magirazi.
-Kana ukapinzwa netsaona kana kufemerwa, tsvaga kurapwa uye upe matanho akakodzera erubatsiro rwekutanga.
-Panguva yekuchengetedza, 2-Fluoro-5-nitropyridine inofanira kuchengetwa munzvimbo yakaoma, inotonhorera, kure nemoto uye oxidizing agents.
