Description

Ethylenebis(Chloroformate) Puriss 98 is a high-purity, bifunctional chloroformate reagent widely used as a versatile building block in organic synthesis. Its primary value lies in its ability to act as a linker or activating agent for the synthesis of carbonates, urethanes, and other functional polymers and fine chemicals. This product is essential for research and development laboratories, as well as production facilities in the pharmaceutical, agrochemical, and specialty polymer industries that require reliable, high-quality intermediates for critical synthesis steps.

Application

• Pharmaceutical Intermediate: Key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for creating carbonate and urethane linkages in prodrugs and polymer-drug conjugates.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of polycarbonates, polyurethanes, and other specialty polymers with tailored properties.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and insecticides where its bifunctionality allows for the construction of complex molecular architectures.
• Chemical Research: A valuable tool in organic synthesis for protecting groups and as a precursor to other reactive intermediates like carbamoyl chlorides.
• Surface Modification: Employed to functionalize surfaces or materials by introducing reactive carbonate groups for further chemical attachment.

Quality Control

Our Ethylenebis(Chloroformate) Puriss 98 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity Puriss grade specifications, typically referenced against in-house or industry-standard methods. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request, providing full traceability and quality assurance for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its properties as a strong acid/organic solvent and high volatility, keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols. Use appropriate corrosion-resistant storage equipment.
