Description

2-Ethyl-4-Fluoroaniline is a versatile fluorinated aromatic amine intermediate of significant importance in advanced organic synthesis. Its value lies in the unique reactivity conferred by the ethyl and fluoro substituents on the aniline ring, enabling precise molecular construction. This compound is primarily needed by the pharmaceutical and agrochemical industries for the development of active ingredients, as well as by research institutions and fine chemical manufacturers.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those targeting central nervous system and anti-inflammatory applications.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atom enhances biological activity and environmental stability.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing fluorinated compounds used in electronic displays and organic light-emitting diodes.
• Dye and Pigment Manufacturing: Employed in the creation of specialized, light-fast dyes and pigments for high-performance applications.
• Polymer Chemistry: Acts as a monomer or curing agent modifier in the production of specialty polymers, such as polyimides and epoxy resins, to alter thermal and chemical resistance.
• Research & Development: A valuable reagent for academic and industrial R&D in medicinal chemistry and material science for structure-activity relationship (SAR) studies.

Quality Control

Our 2-Ethyl-4-Fluoroaniline is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
