Description

4-Ethyl-2-Fluoroaniline is a specialized fluorinated aromatic amine building block of significant importance in advanced organic synthesis. This compound matters for its role as a key intermediate in the development of active pharmaceutical ingredients (APIs) and agrochemicals, where the introduction of fluorine and ethyl groups can dramatically alter biological activity and metabolic stability. It is primarily needed by research and development chemists, process scale-up engineers, and manufacturers within the pharmaceutical, agrochemical, and specialty chemical industries.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders and oncology.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the fluorine atom enhances lipophilicity and bioactivity.
• Liquid Crystal & OLED Materials: Serves as a precursor for fluorinated components in electronic display materials and organic light-emitting diodes (OLEDs).
• Dye & Pigment Manufacturing: Employed in the synthesis of specialized, light-fast fluorinated dyes and pigments.
• Polymer Modification: Acts as a monomer or curing agent for creating high-performance, fluorinated polymers with enhanced chemical resistance.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D exploring new fluorination methodologies and structure-activity relationships.

Quality Control

Our 4-Ethyl-2-Fluoroaniline is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider packaging under an inert gas such as nitrogen or argon.
