Description

2,2,3,3-Tetrafluoropropyl 4-Toluenesulfonate is a specialized fluorinated sulfonate ester, a high-value building block in advanced organic synthesis. Its core value lies in its ability to introduce the reactive tetrafluoropropyl group into target molecules, enabling the creation of novel materials with unique properties. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require precise fluorination to develop new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key reagent in the synthesis of fluorinated active pharmaceutical ingredients (APIs), where fluorine atoms are introduced to enhance metabolic stability, bioavailability, and membrane permeability.
• Agrochemical Synthesis: Used to create novel fluorinated pesticides and herbicides, leveraging fluorine's ability to improve lipophilicity, photostability, and biological activity.
• Liquid Crystal & OLED Material Production: Serves as a precursor for fluorinated components in electronic display materials, contributing to improved dielectric anisotropy, thermal stability, and performance.
• Polymer & Resin Modification: Employed to incorporate fluorinated side chains into polymers, enhancing properties such as chemical resistance, thermal stability, and surface characteristics (low surface energy).
• Organic Synthesis Building Block: Acts as a versatile alkylating agent in nucleophilic substitution reactions for the preparation of complex fluorinated organic molecules in R&D laboratories.
• Surface Treatment Agent Precursor: Used in the development of fluorinated surfactants and coatings that provide oil, water, and stain repellency.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and the absence of critical impurities. We maintain strict in-process controls and final release specifications. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data (HPLC, GC, NMR, IR) are available upon request to support your quality assurance and regulatory documentation 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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
