2-3-Dimethyl pyrazine (CAS#5910-89-4)

Okwu mmalite

2, 3-Dimethylpyrazine bụ ngwakọta organic. Ndị a bụ mmalite nke ụfọdụ akụrụngwa ya, ojiji ya, ụzọ nrụpụta ya na ozi nchekwa:

Ogo:

2, 3-Dimethylpyrazine bụ ihe siri ike na-acha odo odo na-acha odo odo. Ọ nwere isi nke acetone ma ọ bụ ethers ma nwee ike igbari ya na mmanya na ihe mgbaze ether.

Jiri:

2, 3-Dimethylpyrazine na-ejikarị dị ka ihe mmalite maka njikọ organic. Enwere ike iji ya dị ka ihe na-akpali akpali maka esterification, carboxylation na enolation n'okpuru ọnọdụ alkaline.

Usoro:

2, 3-dimethylpyrazine nwere ike ịkwado site na SN2 nnọchi nke ethyl iododide ma ọ bụ ethyl bromide na 2-aminopyrazine. A na-emekarị ọnọdụ mmeghachi omume n'ihu ọnụnọ nke etiti alkaline, dị ka sodium ethoxide. Mgbe mmeghachi omume ahụ gasịrị, a na-enweta ngwaahịa ezubere iche site na kristal ma ọ bụ mmịpụta.

Ozi nchekwa:

2, 3-Dimethylpyrazine nwere obere toxicity n'okpuru ọnọdụ ojiji nkịtị. Dị ka kemikal, kọntaktị na akpụkpọ ahụ, anya, na akụkụ iku ume nwere ike ịkpata mgbakasị ahụ. Ekwesịrị ịgbaso ụkpụrụ nchekwa nchekwa ụlọ nyocha oge niile dị ka iyi uwe ụlọ nyocha, enyo enyo, na akụrụngwa nchebe iku ume mgbe ejiri ya. Ọ bụrụ na enwere kọntaktị na mberede ma ọ bụ iku ume, saa ma ọ bụ wepụ ebe ahụ emetụtara ozugbo wee chọọ ndụmọdụ ahụike.
