Description

4-Bromopyridine CAS NO 1120-87-2 is a versatile halogenated pyridine derivative that serves as a critical building block in advanced organic synthesis. Its value lies in the reactive bromine atom, which facilitates efficient cross-coupling reactions and functional group transformations. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries seeking to develop novel active ingredients and complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs targeting the central nervous system and anti-infectives.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the pyridine core provides bioactivity.
• Ligand and Catalyst Preparation: Serves as a starting material for synthesizing specialized ligands used in homogeneous catalysis and metal-organic frameworks (MOFs).
• Material Science Research: Employed in the development of organic electronic materials, liquid crystals, and photoactive compounds.
• Cross-Coupling Reactions: A fundamental substrate for Suzuki, Stille, and Negishi coupling reactions to form biaryl and heterobiaryl structures.
• Nucleophilic Substitution: The bromine atom is readily displaced by various nucleophiles, enabling the introduction of amines, alkoxides, and other functional groups.
