Description

3-Fluoro-5-(Pentafluorosulphur)Benzylalcohol CAS NO 1240257-89-9 is a high-value fluorinated benzyl alcohol derivative, distinguished by its unique pentafluorosulfur (SF5) functional group. This compound is critical for introducing both fluorine and the highly electronegative, lipophilic SF5 moiety into advanced molecular architectures, significantly altering physical and biological properties. It serves as a key synthetic intermediate for researchers and manufacturers in the pharmaceutical and agrochemical sectors, enabling the development of novel active ingredients with enhanced metabolic stability and bioavailability.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders, oncology, and anti-infectives, where the SF5 group can improve potency and pharmacokinetic profiles.
• Agrochemical Research: Used in developing next-generation herbicides, fungicides, and insecticides, where the introduction of fluorine and SF5 groups can lead to compounds with higher activity, selectivity, and environmental compatibility.
• Liquid Crystal & Electronic Materials: Serves as a precursor for fluorinated components in liquid crystal displays (LCDs) and organic semiconductors, where its properties can influence dielectric constant and molecular alignment.
• Advanced Polymer Chemistry: Employed to synthesize specialty fluorinated monomers and polymers, resulting in materials with enhanced chemical resistance, thermal stability, and unique surface properties.
• Positron Emission Tomography (PET) Tracer Development: The fluorine-18 isotope can be incorporated for use as a radiolabeled precursor in developing diagnostic imaging agents.
• Organic Synthesis & Catalysis: Acts as a versatile reagent or ligand precursor in asymmetric synthesis and cross-coupling reactions facilitated by transition metal catalysts.

Quality Control

Every batch of 3-Fluoro-5-(Pentafluorosulphur)Benzylalcohol is manufactured under strict quality management systems. We employ advanced analytical techniques including HPLC, GC, NMR, and MS to ensure identity, purity, and consistency. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
