Description

3-Chloro-5-(Pentafluorosulfur)Benzoic Acid is a high-value, multi-functional fluorinated aromatic building block essential for advanced chemical synthesis. Its unique structure, featuring both a chloro substituent and a highly electronegative pentafluorosulfur (SF5) group, makes it a critical intermediate for developing novel compounds with enhanced properties. This specialty chemical is primarily sought by research and development teams in the pharmaceutical and agrochemical sectors for creating new active ingredients, as well as by material scientists working on advanced polymers and liquid crystals.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring the unique lipophilicity and metabolic stability imparted by the SF5 group.
• Agrochemical Research: Used in developing next-generation herbicides, fungicides, and insecticides where the SF5 moiety can improve bioactivity and environmental profile.
• Advanced Material Synthesis: Serves as a precursor for specialty monomers and ligands used in high-performance polymers, liquid crystals, and electronic materials.
• Organic Synthesis & Catalysis: A versatile reagent in cross-coupling reactions and as a precursor for generating novel ligands in transition metal catalysis.
• Chemical Biology Probes: Utilized in medicinal chemistry to create molecular probes for studying biological targets and pathways.

Quality Control

Every batch of 3-Chloro-5-(Pentafluorosulfur)Benzoic Acid is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure the material meets the precise requirements for research and scale-up applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (by HPLC/NMR), identity confirmation, and impurity profiles. Our quality commitment supports compliance in regulated research environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). This compound is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere if possible to maximize shelf life and stability.
