diazotization

Diazotization is a chemical process where a primary aromatic amine (a type of compound with nitrogen) is converted into a diazonium salt by reacting with nitrous acid (HNO₂). This reaction typically occurs under cold conditions. The resulting diazonium salt is a reactive intermediate useful in further chemical reactions, especially in dye and dyeing agent production. It allows for the attachment of the nitrogen group to other molecules, enabling the synthesis of various dyes and chemicals. Essentially, diazotization transforms an amine into a versatile building block for creating vivid dyes and other compounds.
