(2-Bromo-pyridin-4-yl)-acetic acid methyl ester is primarily used in organic synthesis as a versatile intermediate for the preparation of more complex chemical compounds. It serves as a key building block in the development of pharmaceuticals, particularly in the synthesis of active pharmaceutical ingredients (APIs) that target various diseases. The bromo and ester functional groups make it a valuable precursor for cross-coupling reactions, such as Suzuki or Heck reactions, which are widely employed in drug discovery and development. Additionally, it is utilized in the synthesis of agrochemicals, where it contributes to the creation of compounds with herbicidal or pesticidal properties. Its role in material science is also notable, as it can be used to modify or create polymers with specific properties for industrial applications.
