Description

(S)-1-(2,5-Difluorophenyl)Ethanol is a high-value chiral building block and intermediate of significant importance in advanced organic synthesis. Its enantiopure (S)-configuration and difluorinated aromatic structure make it a critical precursor for the development of active pharmaceutical ingredients (APIs) and agrochemicals. This compound is essential for research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to incorporate chiral, fluorinated motifs into their target molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and oncology research.
• Agrochemical Synthesis: Used in the production of advanced, fluorinated pesticides and herbicides where the chiral center influences biological activity.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis.
• Material Science Research: Employed in the development of specialty polymers and liquid crystals with unique optical properties.
• Academic & R&D: A valuable reagent for methodological studies in fluorination chemistry and stereoselective transformations.
