Nhanganyaya
2-Fluoro-3-chloro-5-bromopyridine is an organic compound.
Mushonga wacho wakasimba uye kuchena kusvika kuchiedza checrystalline chitarisiko. Hainyungudike mumvura pane tembiricha yemumba, asi inogona kunyungudika mune zvimwe organic solvents senge methanol uye methylene chloride.
3-Bromo-5-chloro-6-fluoropyridine ine imwe kukosha kwekushandisa mune organic synthesis. Inowanzo shandiswa seyepakati kune akasiyana maitiro mune organic synthesis, senge coupling maitiro uye inonhuhwirira hydrocarbon functionalization maitiro. Aya maitiro anogona kuita basa rakakosha mukuvakwa kwezvakaoma organic mamorekuru zvimiro.
Nzira yekugadzirira 3-bromo-5-chloro-6-fluoropyridine inogona kuitwa nenzira dzakasiyana-siyana. Nzira yakajairika ndeyekuita nhanho yehalogenation reaction kuburikidza neinopindirana inotsiva yepyridine, kutanga kuunza fluorine pachinzvimbo 3, ipapo chlorine pachinzvimbo chechishanu, uye pakupedzisira bromine pachinzvimbo chechitanhatu.
Ruzivo rwekuchengetedza: 3-Bromo-5-chloro-6-fluoropyridine ikemikari uye inofanirwa kubatwa zvinoenderana nekuchengetedza kwakakodzera maitiro ekushandisa. Inogona kutsamwisa ganda, maziso, uye nzira yekufema, uye midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa kana uchishanda.
Kuchengetwa uye kubata kwemakemikari kunofanirwawo kuitwa zvinoenderana nemirairo yakakodzera, uye kurongeka uye kunyorwa zvinoenderana nehunhu hwemuviri wemakemikari. Mukushandisa, iva nechokwadi chekufefetedza kwakaringana uye dzivisa kufemesa magasi kana mamhute.
