o-Anisaldehyde Usage And Synthesis

Description

O-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.
