Description

3-Fluoro-2-Formylbenzoic Acid is a high-value aromatic building block featuring both a carboxylic acid and a formyl group on a fluorinated benzene ring. This unique bifunctional structure makes it a critical intermediate for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical and agrochemical R&D teams for constructing novel active ingredients and by material scientists exploring specialty polymers.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a fluorinated benzoic acid scaffold.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides where the fluorine atom enhances biological activity and stability.
• Ligand and Catalyst Development: Serves as a starting material for creating sophisticated chelating ligands and organocatalysts in asymmetric synthesis.
• Material Science Research: Building block for novel monomers in the development of high-performance polymers, liquid crystals, and organic electronic materials.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and fluorescent tags for diagnostic and research applications.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific custom synthesis projects.

Quality Control

Every batch of 3-Fluoro-2-Formylbenzoic Acid is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the precise requirements of your synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profiles as determined by advanced chromatographic and spectroscopic methods.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
