Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for easy modification in organic synthesis, making it valuable in developing compounds with enhanced biological activity. Also employed in research settings for studying reaction mechanisms involving cinnamic acid derivatives. Shows potential in agrochemical applications as a building block for herbicides and plant growth regulators. Its trans configuration enhances stability and reactivity in photochemical and thermal processes.
