2-(Naphthalen-2-yl)-2-(pentyloxy)acetonitrile serves as a versatile dye employed in numerous applications. Dyes are crucial in biological experiments, aiding in the observation and analysis of cell structures, tracking of biomolecules, evaluation of cell functions, differentiation of cell types, detection of biomolecules, investigation of tissue pathology, and monitoring of microorganisms. Their utility extends beyond fundamental scientific research to encompass a broad spectrum of clinical diagnostics. Additionally, dyes find widespread use in traditional arenas like textile dyeing and in newer domains including functional textile processing, food coloring, and dye-sensitized solar cells.
