Description

Methylenecyclopropane; >98%Discontinued is a highly specialized, strained-ring organic compound featuring a cyclopropane ring with an exocyclic methylene group. This unique structure makes it a valuable and reactive intermediate in advanced organic synthesis and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists in the fine chemical, agrochemical, and pharmaceutical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those containing cyclopropane motifs known for metabolic stability.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the strained ring can impart unique biological activity.
• Material Science Research: Acts as a monomer or precursor in the development of specialized polymers and advanced materials with tailored properties.
• Organic Synthesis Reagent: Employed in cycloaddition reactions, ring-opening polymerizations, and other transformations to introduce the methylenecyclopropyl unit into target molecules.
• Academic & Industrial R&D: A critical reagent for methodological studies in catalysis and the exploration of new reaction pathways involving strained olefins.

Quality Control

Every batch of Methylenecyclopropane is produced and analyzed under stringent quality protocols to ensure consistency and reliability for research applications. Our standard grade offers a minimum purity of >98% (typically by GC analysis). Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided to support your regulatory and research documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated place, ideally at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flames. Containers must be kept tightly sealed when not in use to prevent evaporation and potential pressure build-up.
