Description

2,2,3,3,4,4-Hexafluoropentane-1,5-Diyl Bis(4-Methylbenzenesulfonate) is a high-value fluorinated building block and sulfonate ester derivative critical for advanced organic synthesis. This compound matters for its role as a key precursor in the development of sophisticated fluorinated materials and active pharmaceutical ingredients (APIs), where its unique structure imparts desirable properties like enhanced stability and lipophilicity. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty materials industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a versatile building block for the synthesis of fluorinated drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Synthesis: Used in the development of novel, potent herbicides and pesticides where fluorine atoms enhance biological activity and environmental persistence.
• Liquid Crystal & OLED Material Precursor: A key starting material for synthesizing fluorinated components in advanced display and lighting technologies.
• Polymer & Specialty Material Modifier: Incorporated to create fluorinated polymers with improved chemical resistance, thermal stability, and surface properties.
• Cross-linking Agent: Utilized in the preparation of specialty resins and coatings due to its bifunctional sulfonate ester groups.
• Organic Synthesis Reagent: Acts as an alkylating agent or linker in multi-step synthetic routes for complex organic molecules.

Quality Control

Our 2,2,3,3,4,4-Hexafluoropentane-1,5-Diyl Bis(4-Methylbenzenesulfonate) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and GC, to ensure high purity and batch-to-batch consistency suitable for demanding R&D and scale-up processes. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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.
