General description

2-Undecanone occurs naturally in wild tomato. It is also found in Ruta chalepensis essential oil and hop oil. Due to its insect repellant activity, 2-undecanone is being considered as a natural non-toxic alternative to N,N-diethyl-3-methylbenzamide or DEET.
We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is Biobased and thus aligns with "Less Hazardous Chemical Syntheses" and "Use of Renewable Feedstocks".

Application

  • Larvicididal Activity of Natural Repellents Against the Dengue Vector, Aedes aegypti: This paper details the use of natural compounds like 2-Undecanone as effective larvicidal agents against vectors of significant human diseases, showcasing their role in developing non-toxic, eco-friendly insect control solutions (Zhang et al., 2020).

  • Control of Filth Flies, Cochliomyia macellaria (Diptera: Calliphoridae), Musca domestica (Diptera: Muscidae), and Sarcophaga bullata (Diptera: Sarcophagidae), Using Novel Plant-Derived Methyl Ketones: Investigates the efficacy of 2-Undecanone in managing common pest flies, underlining its potential as a biopesticide and organic solvent in public health and safety applications (Deguenon et al., 2019).
