Description

Pyridazine, 3-Bromo- (9Ci) is a halogenated heterocyclic compound that serves as a versatile and valuable building block in advanced organic synthesis. Its core value lies in the reactivity of the bromine atom, which enables efficient cross-coupling reactions and functional group transformations. This intermediate is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the development of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and infectious diseases.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides, leveraging the pyridazine scaffold's bioactivity.
• Material Science Research: Serves as a monomer or functionalizing agent in the creation of specialized polymers and organic electronic materials.
• Ligand and Catalyst Development: Employed to construct complex nitrogen-containing ligands for transition metal catalysis.
• Academic & Contract Research: Essential reagent for methodological studies in cross-coupling (e.g., Suzuki, Stille) and nucleophilic substitution reactions.
• Fine Chemical Production: Intermediate for the custom synthesis of complex, high-value specialty chemicals for various industrial applications.
