3,4-dimethoxycinnamic acid; CAS No.: 14737-89-4; 3,4-dimethoxycinnamic acid. PROPERTIES: This dimethoxy-substituted cinnamic acid features molecular formula C??H??O? with molecular weight 190.18 g/mol. It generally appears as a white crystalline powder. Soluble in polar protic solvents like methanol and water. Melting point approximately 140-145 C. Exhibits IR absorption for carboxylic acid (~2900-2500 cm??) and hydroxyl groups (~3300 cm??). Thermogravimetric analysis indicates decomposition above 180 C under nitrogen. For optimal stability, store at 2-8 C in tightly sealed containers with desiccant, protected from light. The compound may cause mild skin irritation and serious eye damage; therefore, standard laboratory safety precautions including protective clothing and eye protection are recommended during handling. APPLICATIONS: As a dimethoxy-substituted cinnamic acid, 3,4-dimethoxycinnamic acid is predominantly utilized in the synthesis of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a key intermediate in constructing the acetylhydroxamic acid portion of these compounds, where the methoxy groups provide enhanced binding affinity for cyclooxygenase enzymes as demonstrated in medicinal chemistry research (Journal of Medicinal Chemistry). Additionally, the compound participates in the development of fluorescent probes for bioimaging applications, where its cinnamic acid functionality enables conjugation to biomolecules via amide bond formation (Bioconjugate Chemistry). In materials science, it functions as a monomer for preparing polyurethane foams with enhanced thermal stability, where the methoxy substituents contribute to improved flame retardancy and mechanical properties (Polymer International).
