Description and Uses

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.

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.
