Description

Benzaldehyde, 3-Ethyl-4-Fluoro- (9Ci) is a specialized fluorinated aromatic aldehyde building block of significant interest in advanced organic synthesis. This compound matters for its unique molecular architecture, which combines the reactivity of an aldehyde group with the electronic and steric influences of ethyl and fluorine substituents on the benzene ring. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for constructing complex molecules, particularly in the development of new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the preparation of novel drug candidates, especially in medicinal chemistry programs targeting CNS disorders, anti-inflammatory agents, and antimicrobials.
• Agrochemical Synthesis: Used in the research and development of next-generation herbicides, fungicides, and pesticides, where the fluorine atom can enhance biological activity and metabolic stability.
• Liquid Crystal & OLED Material Precursor: Serves as a building block for fluorinated aromatic cores in electronic materials, contributing to improved performance in display and lighting technologies.
• Fine Chemical & Flavor/Fragrance Research: Employed in the synthesis of complex, fluorinated aromatic compounds for specialty chemical applications and novel aroma molecules.
• Academic & Contract Research: Utilized in universities and CROs for methodological development in organic synthesis, particularly studies on directed ortho metalation and cross-coupling reactions involving fluorinated arenes.
