Description

Benzenamine, n-Ethyl-3,5-Difluoro- (9Ci) is a specialized fluorinated aniline derivative, serving as a critical building block in advanced organic synthesis. Its value lies in the strategic placement of fluorine atoms and an ethyl substituent on the aromatic ring, which significantly influences the electronic and steric properties of target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries who require high-purity intermediates for developing novel active ingredients. CAS No. 119284-23-0.

Application

This fluorinated aniline intermediate is designed for high-value synthesis applications, primarily in research and industrial-scale production.

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring fluorinated aromatic motifs to enhance metabolic stability, bioavailability, and binding affinity.
• Agrochemical Synthesis: Building block for developing new-generation herbicides, fungicides, and insecticides, where fluorine incorporation improves lipophilicity and biological activity.
• Material Science Research: Used in the creation of specialty polymers, liquid crystals, and organic electronic materials due to its ability to modify electronic properties.
• Dye and Pigment Chemistry: Intermediate for synthesizing novel fluorinated dyes and pigments with unique color fastness and spectral properties.
• Cross-Coupling Reactions: Serves as a substrate in palladium-catalyzed reactions (e.g., Buchwald-Hartwig amination) for constructing complex nitrogen-containing heterocycles.
