CAS 842-07-9: 1-(Phenylazo)-2-naphthol

Description: 1-(Phenylazo)-2-naphthol, also known as Sudan I, is an organic compound characterized by its azo group (-N=N-) linking a phenyl group to a naphthol moiety. This compound typically appears as a red to reddish-brown solid and is known for its vibrant color, which is a result of the conjugated system present in its structure. It is sparingly soluble in water but soluble in organic solvents such as ethanol and acetone. The compound exhibits properties typical of azo dyes, including the ability to undergo various chemical reactions, such as diazotization and coupling reactions. 1-(Phenylazo)-2-naphthol has applications in dyeing textiles and as a colorant in various products; however, it is important to note that it has been associated with potential health risks, including carcinogenicity, leading to regulatory scrutiny in many regions. Safety precautions are essential when handling this compound, and its use is often restricted in food and cosmetic applications.
