Description

2,3-Difluorophenyl Trifluoromethanesulfonate is a high-value fluorinated building block and reagent used in advanced organic synthesis. This compound matters for its role as a versatile intermediate in constructing complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily needed by R&D chemists and process development scientists working on active pharmaceutical ingredients (APIs), liquid crystal materials, and specialty fine chemicals where the introduction of fluorine atoms or sulfonate ester groups is critical.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially those targeting central nervous system (CNS) disorders and anti-infective agents.
• Agrochemical Synthesis: Used in the development of advanced herbicides and pesticides where fluorinated aromatic structures enhance biological activity and environmental stability.
• Liquid Crystal Materials (LCs): Serves as a precursor for fluorinated liquid crystal compounds used in high-performance displays.
• Cross-Coupling Reactions: An effective electrophile in Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions to form biaryl structures.
• Functional Material Research: Intermediate in the production of organic semiconductors and other electronic materials.
• Chemical Derivatization: Used to introduce the highly reactive trifluoromethanesulfonate (triflate) group for further functionalization.

Quality Control

Our 2,3-Difluorophenyl Trifluoromethanesulfonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) are provided with every shipment, detailing purity, identity, and impurity profiles to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids and organic solvents.
