Formanilide丨CAS 103-70-8

Formanilide is an aromatic amide widely used as an intermediate in organic synthesis, pharmaceuticals, dyes, and fine chemicals. It serves as a key precursor in the preparation of aniline derivatives, heterocyclic compounds, and various bioactive molecules. In pharmaceutical research, formanilide is employed in the synthesis of analgesic, antipyretic, and anti-inflammatory compounds, as well as intermediates for active pharmaceutical ingredients. The compound is also applied in the dye and pigment industry, where it contributes to the synthesis of colorants and specialty chemicals. Additionally, formanilide is used in academic research to study amide formation, acylation reactions, and structure–property relationships of aromatic amides.

Formanilide offers several advantages due to its well-defined chemical structure, stability, and reactivity. The amide functional group provides controlled reactivity, allowing selective transformations such as hydrolysis, substitution, and cyclization. Its aromatic ring contributes to structural rigidity and stability, making it a reliable building block in multi-step synthetic routes. Formanilide is a crystalline solid with good thermal stability and solubility in common organic solvents, facilitating handling, storage, and purification. These characteristics enable reproducible performance and efficient synthesis in both laboratory and industrial environments.
