Diethyl 1,1-cyclopropanedicarboxylate, a compound notable for its clear, colorless liquid appearance and CAS number 1559-02-0, is a cornerstone in modern organic synthesis. Its unique structural features, particularly the strained cyclopropane ring, dictate its chemical behavior and make it an indispensable intermediate for chemists aiming to construct complex molecular architectures.

The chemical properties of Diethyl 1,1-cyclopropanedicarboxylate are defined by its ester functional groups and the inherent strain of its three-membered ring. This strain makes the cyclopropane ring susceptible to nucleophilic attack and ring-opening reactions, facilitating the formation of new carbon-carbon bonds and introducing functional diversity into molecules. For instance, it readily participates in ring-opening addition reactions with various nucleophiles, a fundamental process in building larger organic structures. Its relatively high boiling point and stability under ambient conditions further enhance its utility in laboratory and industrial settings, allowing for controlled reaction conditions.

The applications stemming from these properties are extensive. As a vital intermediate, Diethyl 1,1-cyclopropanedicarboxylate is instrumental in the synthesis of numerous pharmaceuticals. Its use in the production pathways for important drugs such as Ketorolac and Montelukast highlights its significance in human health. Researchers also utilize it in the preparation of alpha-diazo-beta-ketoesters, which are valuable intermediates themselves for various cycloaddition reactions. For any chemical company looking to procure this compound, understanding its reactivity profile is key to optimizing synthetic routes and ensuring high yields.

When sourcing Diethyl 1,1-cyclopropanedicarboxylate, engaging with reputable manufacturers and suppliers is essential. These partners provide not only the necessary purity (typically ≥98%) but also the technical support that researchers and production managers need to effectively utilize the compound. Whether for small-scale R&D projects or large-scale industrial production, the availability of this cyclopropane derivative from trusted sources, often found through a targeted search for a Diethyl 1,1-cyclopropanedicarboxylate manufacturer in China, can significantly streamline development and manufacturing processes.
