一般描述
2-Nonanone is a repulsive odorant and can be detected by the AWB olfactory neurons. It is a medium toxic compound with a rat LD50 of 400–4000 mgkg-1. It is an effective antifungal agent.
应用
2-Nonanone was used to analyze the sensitivity of sensors coated with nafion and carbowax to certify cheese samples. It was used to study binding of β-lactoglobulin to alkanones.

Interactions of the model flavor compound 2-nonanone with individual milk proteins, whey protein isolate (WPI), and sodium caseinate in aqueous solutions were investigated. A method to quantify the free 2-nonanone was developed using headspace solid-phase microextraction followed by gas chromatography
