Description

2-Fluoroethyl Ester Ethanesulfonic Acid is a specialized organofluorine sulfonate ester with significant utility as a key synthetic intermediate. Its value lies in its ability to introduce both a fluoroethyl moiety and a reactive sulfonate ester group, enabling precise molecular modifications in advanced chemical synthesis. This compound is primarily needed by researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries for developing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorine-containing groups to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and pesticides where the fluorine atom enhances biological activity and environmental persistence.
• Liquid Crystal & OLED Material Precursor: Acts as a key reactant in the production of fluorinated components for electronic display and lighting technologies.
• Polymer Modification Agent: Employed to incorporate sulfonate ester functionalities into polymer chains, altering solubility, thermal properties, and surface characteristics.
• Cross-coupling Reagent: Functions as an alkylating agent or a leaving group in palladium-catalyzed and other metal-mediated coupling reactions for C-C and C-heteroatom bond formation.
• Proteomics & Biochemical Research: Utilized as a tool compound or labeling reagent in biochemical studies and proteomic analysis due to its reactive ester group.

Quality Control

Our 2-Fluoroethyl Ester Ethanesulfonic Acid is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and Karl Fischer titration, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 strong bases and oxidizing agents.
