Used primarily in organic synthesis as a reagent for the preparation of nitrite esters, particularly in the conversion of alkyl halides to alkyl nitrites via nucleophilic substitution reactions where it serves as a source of nitrite ions. It can also yield some nitro compounds under certain conditions. Additionally, it is employed in the synthesis of silver-based conductive inks and coatings due to its thermal decomposition into metallic silver. Occasionally used in analytical chemistry for qualitative detection of certain functional groups. Its light sensitivity makes it suitable for limited photographic applications compared to other silver salts. Handle with care as it is shock-sensitive and explosive when dry, especially at high temperatures.
