Description

Sulfuric Acid Bis(2-Fluoroethyl) Ester is a specialized organofluorine compound that serves as a critical building block in advanced chemical synthesis. Its value lies in the unique reactivity imparted by the fluorinated ethyl ester groups, enabling precise molecular modifications. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors who require reliable, high-quality fluorination reagents.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing fluorine-containing motifs to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where fluorination improves efficacy and environmental profile.
• Liquid Crystal & OLED Material Production: Serves as a fluorinated building block for electronic chemicals used in display and lighting technologies.
• Polymer Modification: Employed to introduce fluorinated side chains into polymers, altering surface properties, chemical resistance, and thermal stability.
• Cross-linking Agent: Acts as a difunctional alkylating agent in the preparation of specialty resins and cross-linked materials.
• Organic Synthesis Reagent: Valuable reagent in research laboratories for nucleophilic substitution and esterification reactions under controlled conditions.

Quality Control

Every batch of Sulfuric Acid Bis(2-Fluoroethyl) Ester is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for high-purity chemical intermediates. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee traceability and consistency for your critical processes.

Storage

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