Silver nitrate is a versatile reagent that can be prepared by reacting silver with nitric acid. It is used in various fields such as organic synthesis, photography, silver paints, dyes, chemical analysis, gravimetric analysis, and pharmaceutical preparations.

Silver nitrate can be used as a catalyst in the:

• [3+2]-Cycloaddition of Ͱ-diazocarbonyl compounds with arenediazonium salts to synthesize 2,5-disubstituted tetrazoles.
• Oxidation of aromatic, aliphatic, and conjugated aldehydes to corresponding carboxylic acids in the presence of H₂O₂ as an oxidant.
• Lactamization of methyl Ͱ,Ͱ-disubstituted Ͱ-isocyanoacetates with primary amines to synthesize 3,5,5-trisubstituted imidazolones.

It can also be used as a:

• Reagent to synthesize bisazetanes from the oxidation of azetidine.
