Chemische Eigenschaften
light yellow-green to brown crystalline powder
Occurrence
Reported found in pineapple, beer, wine, grape brandy, rum, many different whisky products, sherry, roasted
barley and hardwood smoke
Verwenden
Syringaldehyde is used in biological studies for the isolation and structural characterization of milled wood lignin, dioxane lignin, and cellulolytic lignin preparation from Brewer''s spent grain.
synthetische
Vanillin is converted to 5-iodovanillin, which is treated with sodium methoxide to form 4-hydroxy-3,5-
dimethyxybenzaldehyde.
Definition
ChEBI: A hydroxybenzaldehyde that is 4-hydroxybenzaldehyde substituted by methoxy groups at positions 3 and 5. Isolated from Pisonia aculeata and Panax japonicus var. major, it exhibits hypoglycemic activity.
Allgemeine Beschreibung
Syringaldehyde is an aromatic phenolic aldehyde and a degradation product of lignin. It exhibits antioxidant activity and is reported to inhibit prostaglandin synthetase enzyme. The synthetic form of syringaldehyde is commercially used in pharmaceuticals, food, cosmetics, textiles, pulp and paper industries.
läuterung methode
Crystallise syringaldehyde from pet ether. [Beilstein 8 H 391, 8 IV 2718.]
