Description

3-Methylpentane-1,5-Diyl Bis(Chloroformate) is a high-purity, reactive chemical intermediate primarily used as a versatile building block in organic synthesis. Its value lies in its ability to act as a bifunctional linker, facilitating the formation of carbonate and urethane bonds under controlled conditions. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, particularly for the synthesis of active pharmaceutical ingredients (APIs), prodrugs, and advanced polymeric materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), prodrugs, and carbonate-based protecting groups.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the production of polycarbonates, polyurethanes, and other specialty polymers.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides, fungicides, and insecticides requiring specific carbonate functionalities.
• Bioconjugation & Prodrug Development: Facilitates the controlled attachment of drug molecules to carriers, antibodies, or release-triggering groups.
• Organic Synthesis Reagent: Employed in laboratory-scale and industrial organic synthesis as a versatile reagent for introducing the chloroformate moiety.
• Material Science Research: Utilized in R&D for developing novel coatings, adhesives, and materials with tailored properties.

Quality Control

Our 3-Methylpentane-1,5-Diyl Bis(Chloroformate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods, 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 needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, amines, and alcohols.
