Description

1,2-Cyclopentanedicarbonyldichloride(9Ci) is a high-purity, reactive diacid chloride derivative of cyclopentane, serving as a critical building block in advanced organic synthesis. Its value lies in enabling the efficient introduction of the cyclopentane-1,2-dicarboxylic acid moiety under mild conditions, which is essential for constructing complex molecular architectures. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty materials industries for creating novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key synthon for the production of novel drug candidates, particularly those containing constrained, bicyclic, or fused ring systems.
• Agrochemical Synthesis: Used in the development of new herbicides, fungicides, and insecticides with enhanced activity and environmental profiles.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for synthesizing specialty polyamides, polyimides, and other high-performance polymers.
• Ligand & Catalyst Development: Precursor for creating chiral ligands and organocatalysts used in asymmetric synthesis.
• Chemical Research: A versatile reagent in academic and industrial R&D for exploring new synthetic methodologies and constructing complex natural product analogs.

Quality Control

Every batch of 1,2-Cyclopentanedicarbonyldichloride(9Ci) is manufactured and tested under strict quality management systems. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is available for each lot, confirming identity, purity, and impurity profiles.

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 maintain product integrity.
