General Description

2,2'-[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(4-ethoxyphenyl)-3-oxobutyramide], also known as Solvent Yellow 14, is a chemical compound commonly used as a yellow coloring agent in various industrial and consumer products, such as plastics, textiles, and inks. It is derived from biphenyl and ethoxyphenyl, and its molecular structure consists of two azo groups linked to a central biphenyl ring. 2,2'-[(3,3'-dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(4-ethoxyphenyl)-3-oxobutyramide] is notable for its strong and stable yellow color, as well as its resistance to fading and degradation when exposed to light and heat. However, like many azo dyes, it has been linked to potential health risks and environmental hazards, and its use is regulated in many countries.
