Beschreibung
o-Methoxybenzaldehyde has a faint, sweet, floral odor. It blends well with cassia. It has a spice-like flavor, quite bitter above 30 - 40 ppm. May be prepared from salicylaldehyde and dimethyl sulfate in weak alkaline solution.
Chemische Eigenschaften
Colorless to cream amber crystalline powder; sweet powdery hawthorn guaiacol vanilla acetophenone almond aroma.
Chemische Eigenschaften
light yellow to pale brown
Occurrence
Reported found in Cassia oil, cinnamon bark, and Cinnamon bark oil (Cinnamomum zeylanicum Blume), Sri Lanka (0.09–0.15%)
Verwenden
Intermediate.
Verwenden
2-Methoxybenzaldehyde has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus. It has also been used to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.

Biochem/physiol Actions
Naturally-occurring aromatic aldehyde with acaricidal activity. May condense with L-tryptophan in foods to form the corresponding phenolic tetrahydro-β-carboline-3-carboxylic acid which is a potent antioxidant.
Sicherheitsprofil
Moderately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes.
