Cas no 142337-95-9 (3-Bromo-5-ethylpyridine)

3-Bromo-5-ethylpyridine is a halogenated pyridine derivative with the molecular formula C7H8BrN. This compound serves as a versatile intermediate in organic synthesis, particularly in pharmaceutical and agrochemical applications. The bromine substituent at the 3-position enhances reactivity for cross-coupling reactions, such as Suzuki or Negishi couplings, while the ethyl group at the 5-position contributes to steric and electronic modulation. Its stable pyridine core ensures compatibility with a range of reaction conditions. The compound is typically supplied as a high-purity solid, suitable for use in fine chemical manufacturing and research. Proper handling under inert conditions is recommended due to its sensitivity to moisture and air.
