Description

4-(Pentafluorosulfanyl)Benzoic Acid is a high-value fluorinated aromatic building block characterized by the unique pentafluorosulfanyl (SF5) group. This compound matters for its exceptional combination of high lipophilicity, thermal stability, and strong electron-withdrawing properties, making it a powerful tool for modulating the physicochemical characteristics of target molecules. It is primarily needed by researchers and process chemists in the pharmaceutical and agrochemical industries for the development of novel active ingredients, as well as in advanced materials science for creating specialty polymers and liquid crystals.

Application

• Pharmaceutical Intermediate: A key synthon for introducing the metabolically stable SF5 moiety into drug candidates to improve membrane permeability and bioavailability.
• Agrochemical Synthesis: Used in the research and development of next-generation herbicides, fungicides, and insecticides where enhanced environmental stability and efficacy are required.
• Liquid Crystal & OLED Materials: Serves as a building block for fluorinated components in electronic display materials and organic light-emitting diodes (OLEDs).
• Polymer Modification: Incorporated into specialty polymers to impart unique surface properties, chemical resistance, and thermal stability.
• Coordination Chemistry & Ligand Design: Utilized to create novel ligands for catalysis, leveraging the strong electron-withdrawing nature of the SF5 group.
• Advanced Material Research: Employed in academic and industrial R&D for exploring new fluorinated compounds with tailored electronic and physical properties.

Quality Control

Our 4-(Pentafluorosulfanyl)Benzoic Acid is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
