Intangiriro
Nibintu kama hamwe na formula ya chimique C7H7N2O3.
Kamere:
ni Ikomeye ifite ibara ry'umuhondo ryijimye kugeza ibara ry'umuhondo. Irashobora gushonga cyane mumashanyarazi kandi ntigabanuke mumazi. Ifite urwego runaka rwo gutwikwa, kandi iyo ishyutswe cyangwa ihuye numuriro ufunguye bizatanga ubumara bwa azote (NOx).
Koresha:
Bikunze gukoreshwa muri synthesis synthesis nkingirakamaro hagati. Irashobora gukoreshwa muguhuza ibice bya pyridine, nka pesticide, ibiyobyabwenge n amarangi. Mubyongeyeho, irashobora kandi gukoreshwa nka ligand kubintu byuma.
Uburyo:
Ubusanzwe itegurwa nigisubizo cya 4-methyl-2-nitropyridine na hydroxide ya sodium. Ubusanzwe reaction ikorwa mumashanyarazi kama kandi ibicuruzwa birashobora kuboneka.
Amakuru yumutekano:
Nibyangiza umubiri wumuntu. Guhura nuruhu bishobora gutera allergique, kandi guhumeka umukungugu cyangwa imyuka bigomba kwirindwa. Mugihe ukemura, hagomba gufatwa ingamba zikwiye zo kurinda, nko kwambara gants, indorerwamo n imyenda ikingira. Iyo ikoreshwa cyangwa ibitswe, igomba kuba kure yumuriro na okiside. Mugihe habaye impanuka, va ahantu hasohotse vuba kandi ufate ingamba zikwiye zo gukora isuku.
