4 6-Dichloro-2-methylpyrimidine (CAS# 1780-26-3) intshayelelo

I-2-Methyl-4,6-dichloropyrimidine, eyaziwa ngokuba yi-2,4,6-trichloropyrimidine okanye i-DCM, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwekhompawundi:

Umgangatho:
- Ukubonakala: I-2-methyl-4,6-dichloropyrimidine i-crystal emhlophe okanye i-crystalline powder engenambala.
- Ukunyibilika: Inonyibiliko oluphantsi emanzini kodwa i-solubility engcono kwizinyibilikisi zendalo.
- Iimpawu zeMichiza: Yikhompawundi ezinzile kakhulu engenakukwazi ukubola okanye ukusabela phantsi kweemeko eziqhelekileyo zokusabela kweekhemikhali.

Sebenzisa:
- I-Solvent: I-2-Methyl-4,6-dichloropyrimidine yinto esetyenziswa ngokuqhelekileyo kwi-solvent ye-organic ehlala isetyenziselwa kwiilebhu zemichiza ukutshabalalisa i-organic compounds, ngakumbi ezo zingaxutywanga emanzini.

Indlela:
- I-2-Methyl-4,6-dichloropyrimidine inokufumaneka ngokusabela kwe-2-methylpyrimidine ngegesi ye-chlorine. Oku kusabela kufuneka kuqhutywe phantsi kweemeko ezifanelekileyo zokungenisa umoya.

Ulwazi ngoKhuseleko:
- I-2-Methyl-4,6-dichloropyrimidine i-organic compound kunye ne-toxicity ethile. Iyacaphukisa kwaye idleka emehlweni, esikhumbeni nakwindlela yokuphefumla. Iiglavu, iiglavu, kunye nezixhobo zokukhusela ukuphefumla kufuneka zinxitywe ngexesha lokusetyenziswa ukuqinisekisa ukungena komoya okwaneleyo. Kwimeko yokungenwa okanye ukuphefumla ngempazamo, funa unyango ngokukhawuleza.
- I-2-Methyl-4,6-dichloropyrimidine ibeka imingcipheko yokusingqongileyo kwaye inetyhefu kwizinto eziphilayo zasemanzini kunye nomhlaba. Xa usebenzisa kwaye ulahla inkunkuma, umgaqo wokukhusela indalo kufuneka ulandelwe, kwaye inkunkuma kufuneka ilahlwe ngokuchanekileyo.

Ngaphambili: Fmoc-D-2-Aminobutyric acid (CAS# 170642-27-0)

Okulandelayo: 3 5-Dibromo-4-(trifluoromethyl)aniline (CAS# 1806274-43-0)
