3 5-Dibromo-2-methylpyridine (CAS# 38749-87-0)

Intshayelelo

I-3,5-Dibromo-2-methylpyriridine i-organic compound kunye ne-chemical formula ye-C6H5Br2N. Isakhiwo kukuba izikhundla ze-2 kunye ne-6 kwindandatho ye-pyridine zithathelwa indawo yi-athomu ye-methyl kunye ne-bromine, ngokulandelanayo.

Indalo:

I-3,5-Dibromo-2-methylpyriridine yikristale engenambala ukuya kwi-yellow yellow kunye nephunga elimnandi. Iqinile kwiqondo lobushushu begumbi kwaye inonyibiliko oluphakathi. Ineqondo lokunyibilika lika 56-58°C kunye neqondo lokubila lika 230-232°C.

Sebenzisa:

I-3,5-Dibromo-2-methylpyriridine isetyenziswa ngokubanzi kwi-organic synthesis. Ingasetyenziswa njenge-reagent ekudibaneni kwezinto ezahlukeneyo zezinto eziphilayo, ezifana neziyobisi, i-pesticides kunye nedayi. Ukongezelela, inokusetyenziswa njengesixhobo sokubhekisela kuhlalutyo lweekhemikhali.

Indlela yokulungiselela:

Indlela yokulungiselela i-3,5-Dibromo-2-methylpyriridine idla ngokuqhutyelwa yi-alkylation reaction kunye ne-bromination reaction ye-pyridine. Okokuqala, i-2-position in pyridine i-methylated kunye ne-methylating agent phantsi kweemeko ezisisiseko ukwenza i-2-picoline. Emva koko, i-2-methylpyridine iphendulwa kunye ne-bromine ukunika imveliso yokugqibela i-3,5-Dibromo-2-methylpyridine.

Ulwazi ngoKhuseleko:

I-3,5-Dibromo-2-methylpyridine iyacasula kwaye iyancipha kwaye idibene ngokuthe ngqo nesikhumba, amehlo kunye neembrane ze-mucous kufuneka zigwenywe. Ngexesha lokusetyenziswa, amanyathelo okukhusela kufuneka athathwe, njengokugqoka iiglasi zokukhusela kunye neiglavu, kunye nokuqinisekisa ukuba umsebenzi wenziwa kwindawo enomoya. Ukongezelela, ikwayinto enokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye neendawo zokushisa eziphezulu. Ukuba uphefumle okanye ufakwe ngempazamo, kufuneka ufune unyango ngexesha.
