Quinoline Yellow SS is a bright yellow dye with green shade. It is insoluble in water, but soluble in nonpolar organic solvents. It may cause contact dermatitis. It has the appearance of a yellow powder with a melting point of 240 °C.

Quinoline Yellow SS is used in spirit lacquers, polystyrene, polycarbonates, polyamides, acrylic resins, and to color hydrocarbon solvents. It is also used in externally applied drugs and cosmetics. Quinoline Yellow SS is used in some yellow colored smoke formulations.

When sulfonated, it forms a water-soluble derivate, Quinoline Yellow WS.
