The atmospheric chemistry of pyruvonitrile, CH₃C(O)CN, was studied experimentally using FTIR smog chamber techniques. All experiments were performed at 296 ± 2 K and 700 Torr. The rate constants k(CH₃C(O)CN + Cl) = (1.01 ± 0.26) × 10^-14 cm³ molecule^-1 s^-1 and k(CH₃C(O)CN + OH) = (3.02 ± 1.11) × 10^-13 cm³ molecule^-1 s^-1 were determined using the relative rate method. NCC(O)OONO₂, ClC(O)OONO₂, CO and HCN were identified as products from the atmospheric degradation of CH₃C(O)CN. The atmospheric lifetime of CH₃C(O)CN was calculated to 38 days and GWP₁₀₀ to 1.
