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

Intangiriro

2, 3-Dimethylpyrazine ni ifumbire mvaruganda. Ibikurikira ni intangiriro kuri bimwe mubintu byayo, ikoreshwa, uburyo bwo gukora namakuru yumutekano:

Ubwiza:

2, 3-Dimethylpyrazine ni ibara ritagira ibara ry'umuhondo kristaline ikomeye. Ifite impumuro ya acetone cyangwa ethers kandi irashobora gushonga muri alcool na ether solver.

Koresha:

2, 3-Dimethylpyrazine ikoreshwa cyane nkibikoresho byo gutangiza synthesis. Irashobora gukoreshwa nkumusemburo wa esterification, carboxylation na enolation mubihe bya alkaline.

Uburyo:

2, 3-dimethylpyrazine irashobora gutegurwa na SN2 isimbuza Ethyl iyode cyangwa Ethyl bromide na 2-aminopyrazine. Imiterere yimyitwarire isanzwe ikorwa imbere ya alkaline, nka sodium ethoxide. Nyuma yo kubyitwaramo, ibicuruzwa bigenewe kuboneka muburyo bwo korohereza cyangwa gukuramo.

Amakuru yumutekano:

2, 3-Dimethylpyrazine ifite uburozi buke mubihe bisanzwe byo gukoresha. Nka miti, guhura nuruhu, amaso, hamwe nubuhumekero bishobora gutera uburakari. Porotokole yumutekano ya laboratoire nko kwambara uturindantoki twa laboratoire ikingira, indorerwamo z'amaso, n'ibikoresho birinda ubuhumekero bigomba gukoreshwa mugihe bikoreshwa. Mugihe uhuye nimpanuka cyangwa guhumeka, oza cyangwa ukureho ako kanya uhite ushakira inama kwa muganga.
