-Bishobora kandi gukoreshwa muguhuza ibindi bintu muri chimie ngengabihe.
Uburyo bwo Gutegura:
- methyl 2, irashobora gutegurwa nintambwe zikurikira:
1. Ubwa mbere, 2,5-dichloronicotinic acide igereranwa na aside aside.
2. Ubusanzwe reaction ikorwa mubihe bya acide, kandi hongerwaho imiti ya esterifike, nka alcool cyangwa catisale ya aside, kugirango hongerwe imbaraga.
3. Igisubizo kimaze kurangira, ibicuruzwa bigenewe biratandukana kandi bigasukurwa bivanze bivanze no kuvoma cyangwa kubikuramo.
Amakuru yumutekano:
- methyl 2, nuruvange rurakaza rushobora kugira ingaruka mbi kumaso, uruhu hamwe nibibyimba.
-Wambare ibikoresho bikwiye byo kurinda nkikirahure, gants hamwe n imyenda ikingira mugihe ukoresha no gukoresha.
-Bigomba kuba kure yumuriro nubushyuhe bwo hejuru kugirango birinde ibyago byumuriro no guturika.
-Iyo kubika no gutunganya, kurikiza byimazeyo inzira yumutekano kugirango wirinde kuvanga no guhura nibindi bintu.
-Niba winjiye cyangwa uhumeka, shakisha ubuvuzi bwihuse hanyuma utange urupapuro rwumutekano cyangwa ikirango cyimiti.
