Description and Uses

p-Methoxybenzaldehyde has a characteristic hawthorne odor and a pungent, anise-like flavor. It has a bitter flavor above 30 - 40 ppm. May be prepared by methylation and oxidation of p-cresol and also by oxidation of anethole.

Perfumery and toilet soaps; odor resembles that of coumarin, but the aldehyde must be mixed with other odorous substances to yield an agreeable odor. Also used in organic syntheses.
