Description

Fluorothioacetic Acid S-Phenyl Ester is a specialized organosulfur and organofluorine compound that serves as a versatile building block in advanced chemical synthesis. Its unique structure, featuring both fluorine and a thioester group, makes it a valuable reagent for introducing fluorinated moieties and sulfur-based functional groups into target molecules. This high-purity intermediate is primarily sought by research and development teams in the pharmaceutical and agrochemical industries for creating novel active ingredients and exploring new synthetic pathways.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of fluorinated drug candidates, particularly in protease inhibitor and kinase inhibitor research.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the fluorine atom enhances biological activity and environmental stability.
• Material Science Research: Acts as a precursor for creating fluorinated polymers or surface-modifying agents with specific hydrophobic or oleophobic properties.
• Ligand and Catalyst Development: Employed in organometallic chemistry to synthesize novel sulfur- and fluorine-containing ligands for catalytic applications.
• Chemical Biology Probes: Useful for labeling or modifying biomolecules to study protein function and interaction mechanisms.
• Custom Synthesis: Serves as a starting material for contract research organizations (CROs) and fine chemical manufacturers producing bespoke compounds for clients.

Quality Control

Every batch of Fluorothioacetic Acid S-Phenyl Ester is manufactured under strict quality management protocols. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for research and process development. A detailed Certificate of Analysis (COA) is supplied with each shipment, confirming identity, purity, and impurity profiles as determined by advanced chromatographic and spectroscopic methods.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents. Use appropriate corrosion-resistant storage containers.
