Nhanganyaya

3,5-Dibromo-2-methylpyriridine isimbi yakagadzirwa nemakemikari yeC6H5Br2N. Chimiro ndechekuti 2 uye 6 nzvimbo pane pyridine mhete inotsiviwa nemethyl uye bromine maatomu, zvichiteerana.

Zvakasikwa:

3,5-Dibromo-2-methylpyriridine ikristaro isina ruvara kune yakachenuruka uye inonhuwa. Iyo yakasimba pakudziya kwekamuri uye ine pakati nepakati solubility. Iine nzvimbo yekunyunguduka inosvika 56-58°C uye painofashaira inosvika 230-232°C.

Shandisa:

3,5-Dibromo-2-methylpyriridine inoshandiswa zvakanyanya mune organic synthesis. Inogona kushandiswa se reagent mukubatanidzwa kwezvinhu zvakasiyana-siyana zvehupenyu, zvakadai semishonga, mishonga yezvipembenene uye dhayi. Uye zvakare, inogona zvakare kushandiswa sechinhu chinongedzo mukuongorora kwemakemikari.

Kugadzirira nzira:

Nzira yekugadzirira ye3,5-Dibromo-2-methylpyriridine inowanzoitwa nealkylation reaction uye bromination reaction yepyridine. Kutanga, iyo 2-nzvimbo mu pyridine inonzi methylated ne methylating agent pasi pemamiriro ezvinhu ekutanga kuumba 2-picoline. Zvadaro, 2-methylpyridine inobatwa nebromine kuti ipe chigadzirwa chekupedzisira 3,5-Dibromo-2-methylpyridine.

Zvekuchengetedza

3,5-Dibromo-2-methylpyridine inogumbura uye inoparadza uye yakananga kusangana neganda, maziso uye mucous membranes zvinofanira kudziviswa. Panguva yekushandiswa, matanho ekuzvidzivirira anofanirwa kutorwa, sekupfeka magirazi ekudzivirira uye magirovhosi, uye kuve nechokwadi chekuti kuvhiyiwa kunoitwa munzvimbo ine mhepo inofefetera. Mukuwedzera, ihwowo chinhu chinopisa uye chinofanira kuchengetedzwa kure nemirazvo yakazaruka uye nzvimbo dzekushisa kwepamusoro. Kana ukafemerwa kana ukapinzwa nekukanganisa, unofanirwa kutsvaga kurapwa nenguva.
