Description

3-Fluoro-4-(4-Methoxyphenyl)Benzoic Acid is a high-purity fluorinated aromatic carboxylic acid building block, essential for advanced organic synthesis. Its unique molecular structure, featuring both fluorine and methoxy substituents, makes it a critical intermediate for developing compounds with tailored electronic and steric properties. This product is primarily targeted at research and development teams in the pharmaceutical, agrochemical, and advanced materials sectors seeking to innovate new active ingredients and functional molecules.

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, inflammation, and oncology.
• Agrochemical Research: Used in the development of next-generation herbicides, fungicides, and plant growth regulators, where the fluorine atom can enhance metabolic stability and bioavailability.
• Liquid Crystal & OLED Materials: Serves as a precursor for synthesizing fluorinated aromatic cores used in liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs) to improve performance and stability.
• Polymer Modification: Incorporated as a monomer or additive to create specialty polymers with enhanced thermal stability, chemical resistance, and specific optical properties.
• Chemical Synthesis Reagent: Employed in cross-coupling reactions (e.g., Suzuki, Heck) and as a precursor for more complex fluorinated compounds in academic and industrial research laboratories.

Quality Control

Our 3-Fluoro-4-(4-Methoxyphenyl)Benzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (HPLC), related substances, and residual solvents. Our quality commitment supports applications requiring high-purity intermediates under cGMP and ISO 9001 guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
