Description

1,1-Cyclopropanedicarboxylic Acid is a versatile and highly functionalized cyclopropane derivative, serving as a critical building block in advanced organic synthesis. Its unique strained-ring structure and dual carboxylic acid groups make it a valuable precursor for constructing complex molecular architectures. This compound is essential for research and development chemists in the pharmaceutical, agrochemical, and material science industries, where it is used to introduce the cyclopropane moiety into target molecules.

Application

• Pharmaceutical Intermediates: Key synthon for the development of active pharmaceutical ingredients (APIs), particularly in the synthesis of compounds with constrained geometries.
• Agrochemical Synthesis: Used in the creation of novel herbicides, fungicides, and insecticides that benefit from the metabolic stability of the cyclopropane ring.
• Ligand and Catalyst Development: Serves as a precursor for chiral ligands and organocatalysts used in asymmetric synthesis.
• Polymer and Material Science: A monomer or cross-linking agent for producing specialty polymers with tailored thermal and mechanical properties.
• Academic and Industrial R&D: A fundamental reagent for methodological development in organic chemistry and medicinal chemistry programs.
• Fine Chemical Production: Intermediate in the multi-step synthesis of complex flavors, fragrances, and other high-value chemicals.

Quality Control

Our 1,1-Cyclopropanedicarboxylic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment and is available upon request.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
