It is used in the dye and pigment industry. It is used in document reproduction as these compounds are light sensitive and break down under UV or violet light. It is used in the synthesis of organic compounds. These compounds are used in explosive materials as solid diazonium halides are explosive in nature.
What is diazonium used for?
Diazonium compounds are standard reagents used in synthesis of organic compounds, especially aryl derivatives. Diazonium salts are light sensitive and break down under near UV or violet light. This property has led to their use in document reproduction. In this process, paper or film is coated with a diazonium salt.
How is diazotization done?
Diazotization is an important reaction of 1° amines. In the diazotization process, the NH2 group is changed to a diazonium salt, R–N2+X−. This is done by reaction with nitrous acid (HNO2). The reactive salt is not usually isolated.
