Description

4-(2,3-Dichlorophenyl)Benzoic Acid is a high-purity, halogenated aromatic carboxylic acid building block essential for advanced organic synthesis. Its unique molecular structure, featuring a benzoic acid moiety linked to a dichlorinated phenyl ring, makes it a critical intermediate for creating complex molecules with specific electronic and steric properties. This compound is primarily utilized by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as active pharmaceutical ingredient (API) synthesis and material science research.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders or inflammatory diseases.
• Agrochemical Synthesis: Serves as a precursor in the development of advanced herbicides, fungicides, and insecticides, where the dichlorophenyl group can enhance biological activity and stability.
• Ligand and Catalyst Development: Used in the preparation of specialized ligands for transition metal catalysis, facilitating challenging cross-coupling and other organic transformations.
• Material Science Research: Employed as a monomer or modifying agent in the creation of specialty polymers, liquid crystals, or organic electronic materials.
• Chemical Research & Development: A versatile scaffold in medicinal chemistry for structure-activity relationship (SAR) studies and library synthesis.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of client-specific target molecules.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect purity and handling properties. Keep away from incompatible materials such as strong bases and oxidizing agents.
