  • Applications

    N-Ethylaniline (CAS 103-69-5) is a key intermediate in the production of dyes and pigments for the textile industry, participating in the synthesis of azo dyes and colorants. It is also used as an organic synthesis building block for compounds employed in coatings and printing inks. Additionally, it serves as a building block for pharmaceutical and agrochemical compounds. Furthermore, it acts as a starting material for specialty chemicals in the polymer and plastics sectors. Use is subject to local regulations and formulation limits.
