Description

Cyclohexanecarboxaldehyde, 4-Ethoxy-, trans- (9Ci) is a specialized chiral aldehyde derivative of cyclohexane, characterized by its trans-configuration and ethoxy substituent. This compound matters as a high-value chemical intermediate and building block for synthesizing complex molecules where stereochemistry is critical. It is needed by R&D and production teams in the pharmaceutical and advanced materials sectors for creating active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and anti-inflammatory drug research.
• Agrochemical Synthesis: Used in the development of advanced, stereospecific pesticides and herbicides where the trans-configuration influences biological activity.
• Liquid Crystal & OLED Materials: Serves as a precursor in the production of chiral dopants and organic semiconductors for display and lighting technologies.
• Flavor & Fragrance Chemistry: Employed as a building block for creating complex, nuanced aroma chemicals and flavoring agents.
• Asymmetric Catalysis Research: Utilized as a substrate or ligand precursor in the development of new chiral catalysts for enantioselective synthesis.
• Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce specific stereochemistry and ether linkages into polymer chains.
