Description

1-Methylene-2-Vinylcyclopropane is a highly reactive, strained-ring hydrocarbon building block of significant interest in advanced organic synthesis. Its unique structure, featuring both a cyclopropane ring and terminal olefins, makes it a valuable precursor for constructing complex molecular architectures through cycloaddition and polymerization reactions. This specialty monomer is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for creating novel polymers and fine chemical intermediates.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the development of novel active pharmaceutical ingredients (APIs) and prodrugs with complex carbocyclic frameworks.
• Specialty Polymer Synthesis: Acts as a monomer for the production of polymers with unique thermal and mechanical properties via ring-opening metathesis polymerization (ROMP) or other mechanisms.
• Agrochemical Research: Used in the synthesis of experimental herbicides, fungicides, and insecticides that require strained-ring components for bioactivity.
• Material Science: Employed in the development of advanced polymeric materials, including coatings, adhesives, and composites with tailored performance characteristics.
• Organic Synthesis Building Block: A versatile reagent for [2+2] and other cycloaddition reactions to construct complex, multi-cyclic organic compounds in academic and industrial research.
• Cross-linking Agent: Potential use as a cross-linker in polymer formulations to enhance network density and material stability.

Quality Control

Our 1-Methylene-2-Vinylcyclopropane is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, GC-MS, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting all critical quality parameters. Our quality system is designed to support cGMP and ISO standards for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Keep away from heat, sparks, and open flame. Store only in original, properly sealed containers in a cool, well-ventilated area separate from oxidizing agents.
