Cas no 17282-01-8 (3-Bromo-2-fluoro-5-methylpyridine)

3-Bromo-2-fluoro-5-methylpyridine is a halogenated pyridine derivative with significant utility in pharmaceutical and agrochemical synthesis. Its distinct substitution pattern—bromo at the 3-position, fluoro at the 2-position, and a methyl group at the 5-position—enhances reactivity for cross-coupling reactions, such as Suzuki or Buchwald-Hartwig couplings, facilitating the construction of complex heterocyclic frameworks. The electron-withdrawing fluorine and bromine groups improve electrophilic substitution selectivity, while the methyl group offers steric and electronic modulation. This compound serves as a versatile intermediate in medicinal chemistry, particularly for developing bioactive molecules. High purity and stability under standard conditions ensure reliable performance in synthetic applications.
