Description

1,2-Cyclopropanedicarbonyldichloride,1,2-Dimethyl-,cis-(9Ci) is a high-purity, cis-configured cyclopropane derivative that serves as a versatile and reactive synthetic building block. Its value lies in its ability to introduce the strained, three-membered cyclopropane ring and reactive acid chloride functionalities into target molecules, enabling the synthesis of complex organic architectures. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise stereochemistry and high functional group tolerance in their synthetic routes.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing cyclopropane motifs known for their metabolic stability and conformational rigidity.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the cyclopropane ring can enhance biological activity and environmental persistence.
• Ligand and Catalyst Development: Serves as a starting material for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Polymer and Material Science: Incorporated as a monomer or cross-linking agent to produce polymers with unique thermal and mechanical properties.
• Chemical Research & Development: Employed in academic and industrial R&D for exploring new [2+1] cycloaddition reactions and constructing complex natural product analogs.
• Fine Chemical Production: Utilized in the multi-step synthesis of specialty chemicals, flavors, and fragrances.

Quality Control

Every batch of our 1,2-Cyclopropanedicarbonyldichloride,1,2-Dimethyl-,cis-(9Ci) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemicals and advanced intermediates. Comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, is performed to verify identity, purity, and isomeric composition. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and batch-to-batch consistency for your critical R&D and scale-up processes.

Storage

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