Description

4-Amino-3-Bromo-Benzoic Acid Ethyl Ester is a high-purity, versatile brominated aniline derivative that serves as a critical building block in advanced organic synthesis. Its bifunctional nature, featuring both an amino and an ester group on a brominated aromatic ring, makes it an indispensable intermediate for constructing complex molecular architectures. This compound is primarily utilized by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty chemical sectors for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a substituted aniline or benzoic acid ester core.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and insecticides, where the bromine atom allows for further functionalization.
• Ligand and Catalyst Preparation: Serves as a starting material for synthesizing specialized ligands used in metal-catalyzed coupling reactions.
• Dye and Pigment Manufacturing: Intermediate in the production of complex organic dyes and colorants, leveraging the amino group for chromophore development.
• Material Science Research: Building block for creating novel polymers, liquid crystals, and organic electronic materials.
• Custom Synthesis and Contract Manufacturing: Supplied to fine chemical companies for use in custom synthesis projects and scale-up processes.
