Applications · 6 items

DescriptionO-Anisaldehyde (also 2-methoxybenzaldehyde) is found in cassia oil, cinnamon bark, and cinnamon bark oil. It is a clear colorless liquid with a strong aroma. O-Anisaldehyde is used as a flavor agent in foods including nonalcoholic/alcoholic beverages, baked goods, chewing gum, confections, frozen dairy, fruit ices, hard/soft candy, instant coffee, tea, Jams, jellies, and milk products. O-Anisaldehyde has been used to examine the acaricidal activity of Periploca sepium oil and its active component against Tyrophagus and to obtain good enantioselectivities using Cu(OAc)(2)-bis(oxazolines) via hydrogen bonding in asymmetric Henry reaction.

Descriptiono-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.

OccurrenceReported found in Cassia oil, cinnamon bark, and Cinnamon bark oil (Cinnamomum zeylanicum Blume), Sri Lanka (0.09–0.15%)

Uses2-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.
