Pigment Yellow 10 is commonly used for yellow road markings The compound is synthesized by coupling the diazonium salt derived from dichloroaniline with the pyrazolone. [ 1 ] The structure of the dye, as determined by X-ray crystallography , consists of planar molecule with a C=O bond and two hydrazone groups.
Various medications include tartrazine to give a yellow, orange or green hue to a liquid, capsule, pill, lotion, or gel, primarily for easy identification. [9] Types of pharmaceutical products that may contain tartrazine include vitamins, antacids, cold medications (including cough drops and throat lozenges), lotions and prescription drugs.

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 ...
By varying both of these components, several useful pigments have been produced. [2] A related family of organic pigments are the simpler arylides, which arise from the coupling of mono-diazonium salts with the same coupling partners. The pigments' colors can range from yellow to yellow-green. One common diarylide yellow pigment is Pigment ...
