用途有機合成原料。
説明2,6-Dibromopyridine is a halogenated pyridine compound used as a pharmaceutical intermediate in the synthesis of the migraine drug (Lasmiditan).Lasmiditan is an oral prescription drug used to treat acute migraine headaches with or without aura. It is important to note that it is not used for migraine prevention.
使用2,6-Dibromopyridine is used as a tridentate chelating ligand and in the formation of macrocycles containing the terpyridine moiety. It is also used to produce 6-bromo-2-methoxypyridine.
純化方法Purify 2,6-dibromopyridine by steam distillation, then recrystallise it twice from EtOH. It does not form an HgCl2 salt. [den Hertog & Wibaut Recl Trav Chim Pays Bas 51 381 1932, Beilstein 20/5 V 435.]
