一般描述
Acetaldehyde diethyl acetal is one of the precursors utilized for the synthesis of fragrances and pharmaceutical products.
应用
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.
