Peroxyacetyl nitrate is a peroxyacyl nitrate. It is a secondary pollutant present in photochemical smog.^[1] It is thermally unstable and decomposes into peroxyethanoyl radicals and nitrogen dioxide gas.^[2] It is a lachrymatory substance, meaning that it irritates the lungs and eyes.^[3]

Peroxyacetyl nitrate, or PAN, is an oxidant that is more stable than ozone. Hence, it is more capable of long-range transport than ozone. It serves as a carrier for oxides of nitrogen (NOx) into rural regions and causes ozone formation in the global troposphere.^[1]
