Description

2-Methoxy-5-(Pentafluorosulfur)Phenylaceticacid is a high-value, specialty fluorinated organic building block. This compound matters for its unique structural motif, combining a phenylacetic acid core with methoxy and pentafluorosulfanyl (SF5) substituents, which imparts exceptional metabolic stability, lipophilicity, and electronic properties. It is primarily needed by researchers and process chemists in the pharmaceutical and agrochemical industries for the development of novel active ingredients, particularly in lead optimization and the creation of advanced materials.

Application

• Pharmaceutical Intermediate: A key synthon for the research and development of new drug candidates, especially in medicinal chemistry programs targeting CNS disorders, oncology, and inflammatory diseases.
• Agrochemical Research: Used in the synthesis of novel herbicides, fungicides, and insecticides, where the SF5 group can enhance biological activity and environmental persistence.
• Advanced Material Science: Serves as a precursor for liquid crystals, organic semiconductors, and polymers requiring specific fluorine content for improved performance.
• Chemical Biology Probes: Utilized in the design of molecular probes and tags for studying biological systems due to its distinct spectroscopic signature.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis houses serving the life sciences sector.
