Allgemeine Beschreibung

2-Methyl-3-heptanone is a colorless to light yellow liquid. It is one of the trace taste- and odor-causing organic compounds present in natural water.

Anwendung

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.
