2,3-Difluoroaniline was used in the synthesis of ethyl 2-arylamino-4-trifluoromethylpyrimidine-5-carboxylate.
2,3-Difluoroaniline serves as a valuable building block in medicinal chemistry and agrochemical synthesis, enabling the construction of fluorinated aromatic scaffolds. Its ortho-difluoro substitution pattern enhances metabolic stability and modulates electronic properties, while the primary amine group facilitates straightforward derivatization via coupling, acylation, or diazotization reactions. The compound exhibits good bench stability and is compatible with standard purification techniques, making it well-suited for use in multi-step synthetic sequences.
