Gabatarwa
2,5-Dibromo-4-methylpyridine wani fili ne na kwayoyin halitta. Mai zuwa shine cikakken gabatarwa ga kaddarorin, amfani, hanyoyin shiri da bayanan aminci na wannan fili:
inganci:
2,5-Dibromo-4-methylpyridine mai ƙarfi ne tare da siffofin crystalline mara launi zuwa rawaya. Yana da ƙarfi mai ƙarfi kuma yana narkewa a yawancin kaushi na halitta. Abu ne mara tsayayye wanda ke rushewa cikin sauki a hasken rana.
Amfani:
Ana amfani da wannan fili sau da yawa azaman albarkatun ƙasa da reagent a cikin haɗaɗɗun kwayoyin halitta.
Hanya:
2,5-Dibromo-4-methylpyridine an shirya shi ne ta hanyar amsawar p-toluene da pyridine brominated. P-toluene yana amsawa tare da cuprous bromide don samar da 2-bromotoluene, wanda ke amsawa tare da pyridine a ƙarƙashin catalysis na acid don samar da samfurin ƙarshe.
