Description

3-(4-tert-Butyl-Phenyl)-Propenal is a high-purity organic intermediate characterized by its propenal (acrolein) moiety attached to a tert-butyl substituted phenyl ring. This compound matters as a versatile building block in fine chemical synthesis, offering a reactive aldehyde group and a bulky aromatic substituent for creating specialized molecular architectures. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials sectors for applications such as the synthesis of novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly those requiring lipophilic aromatic groups.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides, where the tert-butyl group can enhance biological activity and stability.
• Organic Light-Emitting Diode (OLED) Materials: Serves as a precursor in the development of electron-transport or host materials for display and lighting technologies.
• Fine Chemical and Flavor/Fragrance Intermediate: Employed in the multi-step synthesis of complex aromatic aldehydes for specialty chemical applications.
• Cross-coupling Reactions: The reactive aldehyde group makes it a suitable substrate for Pd-catalyzed reactions to form more complex conjugated systems.
• Polymer Modification: Acts as a functional monomer or cross-linking agent for introducing aromatic and aldehyde functionality into polymer chains.
