Description
1α,2α-Dimethyl-3-Methylenecyclopropane is a highly specialized, strained-ring organic compound featuring a cyclopropane core with methyl and methylene substituents. This unique structure makes it a valuable and versatile building block in advanced organic synthesis and materials science research. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.
Application
- Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring strained ring systems for biological activity.
- Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides, where its unique carbon skeleton can impart specific modes of action.
- Specialty Polymer Monomer: Acts as a monomer or co-monomer for creating polymers with tailored thermal and mechanical properties due to the ring strain and reactivity of the methylene group.
- Ligand and Catalyst Development: Employed in organometallic chemistry for the preparation of novel ligands and catalysts used in asymmetric synthesis and polymerization processes.
- Fine Chemical Synthesis: Utilized as a sophisticated synthon for constructing complex natural products and other high-value fine chemicals in laboratory-scale and pilot-scale operations.
- Materials Science Research: Investigated for its potential in creating advanced organic electronic materials or as a component in molecular machines due to its structural rigidity and functional handles.

Quality Control
Every batch of 1α,2α-Dimethyl-3-Methylenecyclopropane is produced and analyzed under strict quality management protocols. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, identity, and impurity profiles as confirmed by GC, GC-MS, and NMR. Our quality system is designed to ensure batch-to-batch consistency and reliability for your critical research and development projects.
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 2-8°C or as specified on the label. Keep away from strong acids, oxidizers, and heat sources. Containers should be kept tightly sealed and upright to minimize loss and degradation.
