Description

3-[(2-Fluorophenyl)Thio]Propanoic Acid CAS NO 21243-09-4 is a high-purity organosulfur compound featuring a fluorinated aromatic thioether moiety linked to a propanoic acid chain. This unique structure makes it a valuable and versatile building block for advanced organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It is primarily sought after by R&D chemists and process development scientists in the fine chemical and life science industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon in the synthesis of novel drug candidates, especially those targeting neurological disorders or possessing anti-inflammatory properties.
• Agrochemical Research: Serves as a precursor in the development of new herbicides, fungicides, or insecticides, leveraging the bioactivity of the fluorine and thioether groups.
• Ligand and Catalyst Development: Used to create specialized ligands for metal catalysis or as a component in organocatalysts due to its electron-donating/withdrawing capabilities.
• Material Science: Incorporated into polymers or advanced materials to impart specific chemical resistance, adhesion, or optical properties.
• Chemical Biology Probes: Utilized in the design of molecular probes and tags for studying biological processes and protein interactions.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthesis projects requiring this precise molecular architecture.
