  • Applications

    4-Ethoxybenzaldehyde (CAS 10031-82-0) is primarily used as an intermediate in organic synthesis across several industries. It serves as a building block for aromatic compounds in fragrance and flavor chemistry, acting as a precursor to other odorant and aroma molecules. It is also employed as an intermediate in the synthesis of pharmaceutical and agricultural chemicals. In coatings and inks, it can be used as a starting material for the preparation of specialty resins and dyes. Additionally, it may be used to prepare substituted benzaldehyde derivatives or other building blocks through further transformations.
