  • Applications

    2-Methoxycinnamic acid (CAS 1011-54-7) is primarily used as an intermediate in organic synthesis, enabling the preparation of cinnamate derivatives; it also acts as a building block in fragrance and flavor chemistry, providing precursors for aroma compounds used in perfumery and flavor formulations; in cosmetics and personal care, it may be used to synthesize fragrance components; in coatings and inks, its cinnamate esters can function as monomers or crosslinking precursors for UV-curable systems; in R&D it serves as a starting material for pharmaceutical and agrochemical intermediates and for developing functionalized cinnamic derivatives for polymeric materials.
