Description

Benzoic Acid, 4-Ethoxy-2,3-Difluoro-, Methyl Ester (9Ci) is a high-purity fluorinated aromatic ester, a key advanced intermediate in modern synthetic chemistry. Its precise molecular structure, featuring ethoxy and difluoro substitutions, makes it an essential building block for creating complex molecules with tailored properties. This compound is primarily sought by R&D and production teams in the pharmaceutical and agrochemical sectors for developing new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A critical synthon in the research and synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic cores for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key precursor in the development of next-generation herbicides, fungicides, and pesticides, where the difluoro and ethoxy groups contribute to biological activity and environmental profile.
• Liquid Crystal Materials: Used in the research and production of fluorinated liquid crystals for advanced display technologies (LCDs), where it helps fine-tune dielectric anisotropy and viscosity.
• Organic Electronics: Acts as a building block for electron-transport materials or host materials in OLED (Organic Light-Emitting Diode) research due to its aromatic and fluorinated structure.
• Fine Chemical Synthesis: Employed in custom synthesis and contract manufacturing for creating specialty chemicals, dyes, and complex organic compounds.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic synthesis, including cross-coupling reactions and fluorination studies.
