Used primarily as a dye in industrial applications, especially for coloring solvents, oils, and waxes. Commonly applied in the formulation of printing inks and coatings where a stable green color is required. Also utilized as a colorant in some automotive and aviation fuels to distinguish fuel types and detect contamination. Its solubility in organic solvents makes it suitable for use in non-aqueous systems. Limited use in consumer products due to low biodegradability and potential environmental persistence.
