Widely used as a blue dye in industrial applications, particularly in the coloring of oils, waxes, and greases. It is valued for its strong solubility in non-polar media and stability under high-temperature processing conditions. Commonly applied in the formulation of printing inks and plastics where a robust blue colorant is required. Also utilized in some laboratory settings as a staining agent for visualizing substances in thin-layer chromatography due to its distinct color and affinity for certain organic compounds. Its use is restricted in consumer products due to potential toxicity and lack of biodegradability.
