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

2-Methyl-4,6-dichloropyrimidine, yomwe imadziwikanso kuti 2,4,6-trichloropyrimidine kapena DCM, ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha pawiri:

Ubwino:
- Maonekedwe: 2-methyl-4,6-dichloropyrimidine ndi kristalo woyera kapena wopanda mtundu wa crystalline ufa.
- Kusungunuka: Lili ndi kusungunuka kochepa m'madzi koma kusungunuka bwino mu zosungunulira za organic.
- Chemical properties: Ndi chinthu chokhazikika kwambiri chomwe sichikhoza kuwonongeka kapena kuchitapo kanthu pansi pa zochitika za mankhwala.

Gwiritsani ntchito:
- Zosungunulira: 2-Methyl-4,6-dichloropyrimidine ndizosungunulira zomwe zimagwiritsidwa ntchito nthawi zambiri m'ma laboratories amadzimadzi kuti zisungunuke organic compounds, makamaka zomwe sizisungunuka m'madzi.

Njira:
- 2-Methyl-4,6-dichloropyrimidine angapezeke ndi zimene 2-methylpyrimidine ndi chlorine mpweya. Izi ziyenera kuchitika pansi pa mpweya wokwanira.

Zambiri Zachitetezo:
- 2-Methyl-4,6-dichloropyrimidine ndi organic pawiri ndi kawopsedwe. Zimakwiyitsa komanso zimawononga m'maso, pakhungu, komanso m'mapapo. Magolovesi, magalasi, ndi zida zotetezera kupuma ziyenera kuvalidwa pakagwiritsidwe ntchito kuti mukhale ndi mpweya wokwanira. Ngati mwalowetsedwa mwangozi kapena kupumira mpweya, pitani kuchipatala mwamsanga.
- 2-Methyl-4,6-dichloropyrimidine imayambitsa kuopsa kwa chilengedwe ndipo ndi poizoni kwa zamoyo zam'madzi ndi nthaka. Pogwiritsa ntchito ndi kutaya zinyalala, mfundo yoteteza chilengedwe iyenera kutsatiridwa, ndipo zinyalala ziyenera kutayidwa moyenera.
