Chemical Properties

Colorless clear liquid

Occurrence

Reportedly present in Muscadine grapes (Vitis rotundifolia), cooked chicken and wine (white and rose).

Uses

2-Methyl-3-heptanone was used as an internal standard in dynamic headspace sampling, direct solvent extraction and vacuum simultaneous steam distillation–solvent extraction for sample preparation in volatile compound analysis in Thai soy sauce. It was used as an internal standard in the identification of volatile flavor compounds of stored nonfat dry milk using gas chromatography-olfactometry and aroma extract dilution analysis.

Aroma threshold values

Odor detection threshold in water = 0.024 to 0.058 ppm
