Description

2,5-Dibromopyridine CAS NO 624-28-2 is a versatile brominated heterocyclic building block of significant importance in advanced organic synthesis. Its core value lies in providing a reactive scaffold for the introduction of pyridine-based structures, enabling the construction of complex molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries who require high-purity intermediates for coupling reactions and functional group transformations.

Application

• Key intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly for kinase inhibitors and other small-molecule therapeutics.
• Building block for creating ligands and catalysts used in cross-coupling reactions (e.g., Suzuki, Negishi).
• Precursor in the development of agrochemicals, such as herbicides and fungicides with pyridine cores.
• Starting material for the production of functionalized pyridines used in electronic materials and organic light-emitting diodes (OLEDs).
• Versatile reagent in academic and industrial R&D for exploring novel heterocyclic chemistry and structure-activity relationships.
• Used in the manufacture of liquid crystal compounds and other advanced functional materials.
