4 6-Dichloro-2-methylpyrimidine (CAS # 1780-26-3) Kev taw qhia

2-Methyl-4,6-dichloropyrimidine, tseem hu ua 2,4,6-trichloropyrimidine los yog DCM, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw:

Zoo:
- Cov tsos mob: 2-methyl-4,6-dichloropyrimidine yog cov dawb crystalline hmoov los yog tsis muaj xim crystalline hmoov.
- Solubility: Nws muaj tsawg solubility hauv dej tab sis zoo dua solubility hauv cov kuab tshuaj organic.
- Cov khoom siv tshuaj lom neeg: Nws yog ib qho chaw ruaj khov uas tsis yooj yim rau decomposition lossis cov tshuaj tiv thaiv nyob rau hauv cov pa tshuaj tiv thaiv kab mob.

Siv:
- Cov kuab tshuaj: 2-Methyl-4,6-dichloropyrimidine yog cov organic hnyav uas feem ntau siv hauv cov chaw soj nstuam tshuaj kom yaj cov organic tebchaw, tshwj xeeb tshaj yog cov uas tsis muaj dej nyob hauv dej.

Txoj kev:
- 2-Methyl-4,6-dichloropyrimidine tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm 2-methylpyrimidine nrog cov roj chlorine. Cov tshuaj tiv thaiv no yuav tsum tau ua raws li qhov muaj cua txaus.

Cov ntaub ntawv kev nyab xeeb:
- 2-Methyl-4,6-dichloropyrimidine yog cov organic compound nrog qee yam tshuaj lom. Nws yog irritating thiab corrosive rau lub qhov muag, tawv nqaij, thiab ua pa ib ntsuj av. Cov hnab looj tes, tsom iav, thiab cov cuab yeej tiv thaiv ua pa yuav tsum hnav thaum siv kom muaj cua txaus. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog inhalation, nrhiav kev kho mob tam sim ntawd.
- 2-Methyl-4,6-dichloropyrimidine ua rau muaj kev phom sij rau ib puag ncig thiab muaj tshuaj lom rau cov kab mob hauv dej thiab av. Thaum siv thiab pov tseg cov pov tseg, yuav tsum ua raws li lub hauv paus ntsiab lus ntawm kev tiv thaiv ib puag ncig, thiab cov pov tseg yuav tsum muab pov tseg kom raug.
