N-Boc-2-fluoroaniline, identified by its CAS number 98968-72-0, is a compound of significant interest in the field of organic chemistry due to its unique structural features and versatile reactivity. As a protected fluoroaniline derivative, it serves as a critical intermediate in the synthesis of a wide range of complex molecules, particularly those intended for pharmaceutical and advanced material applications.

The chemical structure of N-Boc-2-fluoroaniline features a tert-butoxycarbonyl (Boc) protecting group on the amine nitrogen and a fluorine atom ortho to it on the phenyl ring. This combination imparts specific chemical properties that are highly valued in synthesis. The Boc group effectively shields the amine during various reaction steps, allowing for selective modifications elsewhere in the molecule. The fluorine atom, known for its electronegativity, can influence the electron density of the aromatic ring, affecting its reactivity in electrophilic aromatic substitution or other reactions.

The typical physical appearance of N-Boc-2-fluoroaniline is that of a white to off-white powder, with a purity level often exceeding 98% as determined by GC analysis. This high purity is essential for its application as a reliable building block in multi-step syntheses where even minor impurities can lead to unwanted side reactions or contaminate the final product. Its solubility characteristics are generally favorable in common organic solvents, facilitating its use in solution-phase chemistry.

The primary application of N-Boc-2-fluoroaniline lies in its role as a key intermediate in organic synthesis. It is widely employed in the pharmaceutical industry for the preparation of active pharmaceutical ingredients (APIs). The fluorinated aniline motif is present in numerous drug candidates and marketed drugs, where the fluorine atom often enhances metabolic stability, lipophilicity, and binding affinity to biological targets. Researchers also utilize this compound in the synthesis of specialty chemicals, agrochemicals, and materials for electronic applications.
