Description

3-(3-Bromo-Phenyl)-Propionic Acid Ethyl Ester is a versatile brominated aromatic ester, serving as a key organic intermediate in advanced chemical synthesis. Its value lies in providing a reactive phenylpropionate backbone with a strategically positioned bromine atom for further functionalization. This compound is essential for research chemists and manufacturers in the pharmaceutical and agrochemical sectors who require high-purity building blocks for developing active ingredients and novel materials.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of non-steroidal anti-inflammatory drugs (NSAIDs) and other active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and plant growth regulators, leveraging the bromine atom for cross-coupling reactions.
• Liquid Crystal & OLED Material Research: Acts as a building block for creating complex aromatic structures used in electronic display technologies.
• Organic Synthesis & Catalysis: Employed in Suzuki, Heck, and other palladium-catalyzed cross-coupling reactions to form biaryl structures.
• Fine Chemical Production: Serves as an intermediate for flavors, fragrances, and specialty polymers requiring bromo-aromatic motifs.
• Academic & R&D Laboratories: Used in methodological studies and for creating custom molecular libraries for drug discovery programs.
