Short summary
In this work, we focus on the atmospheric chemistry and consequences for air quality of 2-methylpentanal (2MP), which is widely used as a flavoring ingredient and as an intermediate in the synthesis of dyes, resins, and pharmaceuticals. Measurements are presented on how fast 2MP is degraded by sunlight and oxidants like hydroxyl (OH) radicals and chlorine (Cl) atoms and what products are generated. We conclude that 2MP will be degraded in a few hours, affecting local air quality.
