Used primarily as an intermediate in organic synthesis, especially in the development of dyes and pigments. It plays a role in the preparation of conjugated systems for optoelectronic materials due to its extended π-electron structure. Also investigated for use in pharmaceutical research as a building block in the synthesis of bioactive compounds with potential antitumor and antimicrobial properties. Its imine and enamine functionalities make it suitable for coordination with metal ions, finding application in the design of metal-organic frameworks and catalysts.
