Description

3-Ethyl-4-Fluoroaniline is a versatile fluorinated aromatic amine building block of significant importance in advanced organic synthesis. Its molecular structure, featuring both an ethyl substituent and a fluorine atom on the aniline ring, makes it a critical intermediate for creating compounds with tailored electronic and steric properties. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in the development of fluorinated drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atom enhances biological activity and stability.
• Liquid Crystal & Electronic Materials: Serves as a precursor for specialty chemicals used in liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).
• Dye and Pigment Manufacturing: Acts as an intermediate for producing specialized fluorinated dyes and pigments with unique color fastness and properties.
• Polymer Modification: Employed in the synthesis of functional monomers and additives to impart specific characteristics to high-performance polymers.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways in medicinal and materials chemistry.

Quality Control

Our 3-Ethyl-4-Fluoroaniline is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory 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). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque or amber packaging during storage and handling.
