| 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.

| Description | 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. |

Lanka (0.09–0.15%) |
| Uses | Intermediate. |

| 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. |
| Safety Profile | Moderately toxic by
ingestion. A skin irritant. Mutation data
reported. Combustible liquid. When heated
to decomposition it emits acrid smoke and
irritating fumes. |
