Quinoline Yellow WS is a mixture of organic compounds derived from the dye Quinoline Yellow SS (Spirit Soluble). Owing to the presence of sulfonate groups, the WS dyes are water-soluble (WS). It is a mixture of disulfonates (principally), monosulfonates and trisulfonates of 2-(2-quinolyl)indan-1,3-dione with a maximum absorption wavelength of 416 nm.
