4-Hydroxy-3-methoxystyrene Chemical Properties,Usage,Production

Chemical Properties 2-Methoxy-4-vinylphenol has a powerful, spicy, apple, rum, roasted peanut aroma.
Occurrence Reported found among the steam-distillable phenols from the alcoholic fermentation of cereal grains, especially corn; probably formed from ferulic acid. Reported found in tobacco, beans, coffee, malt, apple, grapefruit juice, grapes, raspberry, strawberry, asparagus, kohlrabi, carrot, celery, tomato, rye bread, smoked fish, cured pork, beer, cognac, rum, cider, sherry, grape wines, coffee, tea, peanut, popcorn,soybean, passion fruit, beans,starfruit,sesame seed, mango, cauliflower, tamarind, fig, corianderseed, rice, quince, rhubarb, dill, lovage root, corn oil, sweet corn, malt, wort, Texas sage, okra, cuttlefish and Chinese quince.
Uses p-Vinylguaiacol is an aromatic substance and one of the compounds responsible for the natural aroma of buckwheat. It is also one of the major pyrolytic products of (E)-N-[(4-hydroxy-3-methoxy)-phenethyl]-3-[(3-methoxy-4-O-β-D-glucopyranosyloxy) phenyl] acrylamide; a new gycloside in tobacco.
Preparation From vanillin by reacting with acetic anhydride and sodium acetate yielding 3-methoxy-4-hydroxycinnamic acid on sub sequent hydrolysis; the latter, heated with quinoline in the presence of hydroquinone, is decarboxylated to 4-vinylguaiacol.
Definition ChEBI: A member of the class of phenols that is guaiacol in which the hydrogen para- to the hydroxy group is replaced by a vinyl group.
Aroma threshold values Detection; 0.75 to 3 ppb
General Description 2-Methoxy-4-vinylphenol is one of the key volatile aroma compounds of buckwheat and okra.
