Description

Methyl 4-Fluoro-3-Formylbenzoate CAS NO 1093865-65-6 is a high-purity, multi-functional aromatic ester building block designed for advanced organic synthesis. Its unique structure, featuring both a formyl and a fluoro substituent on the benzoate core, makes it a critical intermediate for constructing complex molecules with tailored properties. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries seeking to develop new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for candidates targeting central nervous system (CNS) disorders, inflammation, and oncology.
• Agrochemical Synthesis: Serves as a versatile building block for developing new herbicides, fungicides, and insecticides, where the fluorine atom enhances biological activity and metabolic stability.
• Liquid Crystal & OLED Material Research: Used in the development of advanced electronic materials, where its aromatic and polarizable structure contributes to desired optical and electronic properties.
• Polymer Modification: Employed to introduce functional groups into polymer backbones, enabling the creation of specialty polymers with specific adhesion, solubility, or reactivity characteristics.
• Cross-Coupling Reactions: The formyl group is an ideal handle for further functionalization via reactions like reductive amination or condensation, while the ester allows for hydrolysis or transesterification.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D labs exploring new synthetic methodologies and creating libraries of fluorinated compounds for screening.
