Thallium(I) nitrate, also known as thallous nitrate, is a thallium compound with the formula TlNO₃. It is a colorless and highly toxic salt.

Thallium(I) nitrate can be produced by reacting thallium(I) iodide with nitric acid.^[1]

However, the production is simpler starting from the metal, its hydroxide or the carbonate: ^[2]

${\displaystyle \mathrm{T}\mathrm{l}\mathrm{O}\mathrm{H}\mathrm{+}\mathrm{H}\mathrm{N}{\mathrm{O}}_{\mathrm{3}}\mathrm{⟶}\mathrm{T}\mathrm{l}\mathrm{N}{\mathrm{O}}_{\mathrm{3}}\mathrm{+}{\mathrm{H}}_{\mathrm{2}}\mathrm{O}}$

${\displaystyle \mathrm{T}{\mathrm{l}}_{\mathrm{2}}\mathrm{C}{\mathrm{O}}_{\mathrm{3}}\mathrm{+}\mathrm{2}\mathrm{H}\mathrm{N}{\mathrm{O}}_{\mathrm{3}}\mathrm{⟶}\mathrm{2}\mathrm{T}\mathrm{l}\mathrm{N}{\mathrm{O}}_{\mathrm{3}}\mathrm{+}\mathrm{C}{\mathrm{O}}_{\mathrm{2}}\mathrm{+}{\mathrm{H}}_{\mathrm{2}}\mathrm{O}}$

Thallium(I) nitrate is extremely toxic, like many other thallium compounds. It is highly toxic by ingestion but can also be absorbed through skin due to its solubility in water.^[3]
