3-Bromo-5-hydroxypyridine C??? ??, ??, ??

??

3-bromo-5-hydroxypyridine is an important industrial raw material widely used in medicine, pesticides, dyes, and other industries. Since the pyridine ring has biological activity and plays an irreplaceable role in synthesising drugs that cannot be replaced by other groups or functional groups, it is a hot area in pharmaceutical research. The hydroxyl and bromine atoms in the structure of 3-bromo-5-hydroxypyridine have diverse chemical reactivity. The alcohol hydroxyl unit in its structure can undergo nucleophilic substitution reactions with common alkyl halides under alkaline conditions to obtain corresponding ether derivatives.
