Dyes and pigments have many applications, and their growing development is driven bytheir increased use. As a contribution to this topic, in this work, the synthesis of functionalized pararosaniline was evaluated with the aim to obtain an amphiphilic dye. Pararosaniline is a dye highlysoluble in water and polar solvents, presenting three amino groups in its structure. We realized thatthe functionalization of pararosaniline by direct coupling of amino groups with halogenated fattyacids leads to amides derived from fatty acid. In the synthesis, fatty acid chloride from sunfloweroil and basic catalysts were used. Over a single step one-pot procedure carried out at room temperature in moderate reaction time, a new functionalized pararosaniline was synthesized. The results showed that after derivatization with chloride of fatty acids, the dye exhibits solubility both in water and in non-polar systems with different color intensities.
