Nhanganyaya
2-Bromo-4-methyl-5-nitropyridine is an organic compound. Iyi inotevera sumo kune chimiro chayo, kushandiswa, nzira yekugadzirira uye ruzivo rwekuchengetedza:
Hunhu:
2-Bromo-4-methyl-5-nitropyridine chinhu chakasimba chine makristasi eyero. Patembiricha yemumba, haiwanzo kunyungudika mumvura, asi inogona kunyungudika muorganic solvents senge ethanol uye dimethylformamide.
Shandisa:
Mushonga uyu unowanzoshandiswa sepakati mune organic synthesis. Inogona kushandiswa mukugadzirira kweimwe nitrogen-ine heterocyclic compounds, zvakadai sepyrroles uye indoles.
Nzira:
2-Bromo-4-methyl-5-nitropyridine inogona kugadzirwa nekutsiviwa kwekuita kweaniline. Pasi pemamiriro akakodzera, aniline inobatwa nebromoacetic acid kuti ibudise 2-bromoaniline. Zvadaro, nealkylation pasi pemamiriro e-alkaline, 2-bromoaniline inonzi alkylated kuti iwane 2-bromo-4-methylaniline. Iyo inoguma 2-bromo-4-methylaniline inoiswa nitrification ne nitrification kuti iwane 2-bromo-4-methyl-5-nitropyridine.
Zvekuchengetedza
2-Bromo-4-methyl-5-nitropyridine is organic compound uye inofanira kuchengetwa uye kushandiswa zvakanaka. Icho chinhu chinopisa uye chinofanira kuchengetedzwa kure nemirazvo yakazaruka uye kupisa kwakanyanya. Panguva yekushanda, kusangana neganda, maziso, uye turakiti rekufema kunofanira kudziviswa, uye kushanda kunofanira kuitwa pasi pemamiriro emhepo. Magirovhosi ekudzivirira, magogi uye masks zvinofanirwa kupfekwa kana zvichishandiswa. Kana wasangana netsaona, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa.
