Used in organic synthesis as a building block for complex molecule construction, particularly in the development of pharmaceuticals and agrochemicals. Its conjugated yne-aldehyde structure makes it valuable in carbon-chain extension reactions and cyclization processes. Commonly employed in research settings for creating bioactive compounds and specialty intermediates. Shows reactivity in click chemistry and metal-catalyzed coupling reactions, enabling diverse functionalization. Also explored in fragrance chemistry due to its potential to contribute green or metallic olfactory notes.
