Beschreibung

Allgemeine Beschreibung

Acetaldehyde diethyl acetal is one of the precursors utilized for the synthesis of fragrances and pharmaceutical products.

Anwendung

Acetaldehyde diethyl acetal may be used as a reference standard for the determination of acetaldehyde diethyl acetal in:

• Wine vinegars by headspace sorptive extraction−thermal desorption−gas chromatography−mass spectrometry (HSSE−TD−GC−MS).
• Distilled spirits by GC with flame ionization detection (FID) as well as GC-FID-MS.
• Organic red wines derived from Saccharomyces cerevisiae strains by GC-FID as well as HSSE-GC−MS.
• Cognac (brandy) by HS-GC-MS.
