Description

2-Cyclopropyl-4-Fluoroaniline is a high-purity fluorinated aromatic amine building block of significant interest in advanced organic synthesis. Its core value lies in the unique combination of the cyclopropyl and fluoro substituents, which are critical for modulating the lipophilicity, metabolic stability, and binding affinity of target molecules. This compound is primarily sought after by research and development chemists in the pharmaceutical and agrochemical industries for the creation of novel active ingredients.

Application

• Pharmaceutical Intermediate: A key synthon for the development of active pharmaceutical ingredients (APIs), particularly in kinase inhibitors, antiviral agents, and central nervous system (CNS) drugs.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides, where the fluorine atom enhances bioactivity and environmental persistence.
• Material Science Precursor: Serves as a monomer or functionalization agent in the synthesis of specialty polymers, liquid crystals, and organic electronic materials.
• Chemical Research & Development: Employed in academic and industrial labs for methodological studies in cross-coupling reactions, amide bond formation, and other C-N bond constructing processes.
• Dye and Pigment Intermediate: Acts as a starting material for synthesizing novel fluorinated dyes and pigments with unique optical properties.
