Applicazioni

4-Methoxybenzaldehyde dimethyl acetal is used as a precursor to 1-methoxy-1-(4-methoxyphenyl)hept-2-yne, 2,5-dioxopyrrolidin-1-yl-3-((4R)-2-(4-methoxyphenyl)-5,5-dimethyl-1,3-dioxane-4-carboxamido)propanoate and 1-(p-anisyl)-2-(2-methoxyethyl)-3-phenylindene. Further, it acts as a protecting group reagent for diols, especially in carbohydrates. It is also used as a flavor essence in sunflower, cyclamen and in jasmine. In addition to this, it is involved in allylation reactions with allyltrimethylsilane catalyzed by Iron(III) chloride.

Note

Incompatible with strong oxidizing agents, strong acids and strong bases. Store in a cool place.
