Mushonga wacho une mashandisirwo akakosha mukugadzirwa kwezvinodhaka uye kugadzirwa kwepesticide. Inogona kushandiswa sechinhu chepakati chekugadzirwa kwebiologically active compounds. Semuenzaniso, inogona kushandiswa kugadzira antiviral mishonga nemishonga yezvipembenene, nezvimwe.
Iyo 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine inogona kugadzirwa nenzira dzakasiyana. Nzira yakajairika ndeyekuunza maatomu ebromine uye chlorine mukuita nebromination uye chlorination, zvichiteerana, kutanga nepyridine. Zvadaro, boka retrifluoromethyl rinounzwa mune trifluoromethylation reaction. Iyi synthesis inowanzoitwa pasi pemhepo inert kuti ive nechokwadi chepamusoro kusarudza uye goho rekuita.
Iyo 3-Bromo-2-chloro-5-(trifluoromethyl)pyridine ine ruzivo rushoma rwekuchengetedza. Inogona kunge ichishungurudza maziso, kufema uye ganda. Panguva yekushandiswa, kutarisirwa kunofanira kutorwa kuti usapinda zvakananga neganda nemaziso. Panguva imwecheteyo, matanho ekudzivirira akakodzera anofanira kutorwa panguva yekushanda, sekupfeka magirazi ekudzivirira, magirafu uye zvipfeko zvekudzivirira.
Mukuwedzera, panguva yekubata nekuchengetedza, kutarisirwa kunofanira kutorwa kudzivirira kusangana nezvinhu zvinopisa uye kuchengetedza mhepo yakanaka. Pakurasa marara, mitemo yenzvimbo inofanira kuteverwa uye nzira dzakakodzera dzokurasa tsvina dzinofanira kutorwa. Inonyanya kushandiswa uye inobatwa pasi pekutungamirirwa kwemakemikari ane ruzivo.
