2-Methoxy-4-vinylphenol is an aromatic substance used as a flavoring agent.[1] It is one of the compounds responsible for the natural aroma of buckwheat.[2]
Some insects such as Rhynchophorus ferrugineus (Red palm weevil) use this substance for chemical signaling (pheromones).[3]
The aroma of pure substance was described as: apple, spicy, peanut, wine-like or clove and curry.
Ferulic acid is converted by certain strains of yeast, notably strains used in brewing of wheat beers, such as Saccharomyces delbrueckii (Torulaspora_delbrueckii), to 4-vinyl guaiacol (2-methoxy-4-vinylphenol) which gives beers such as Weissbier and Wit their distinctive "clove" flavour. Saccharomyces cerevisiae (dry baker's yeast) and Pseudomonas fluorescens are also able to convert trans-ferulic acid into 2-methoxy-4-vinylphenol.[4]
