Description

1,2-Cyclopropanedicarbonyl Dichloride, 1-Methyl-, cis- (9Ci) is a highly reactive, functionalized cyclopropane derivative that serves as a critical building block in advanced organic synthesis. Its value lies in the strained cyclopropane ring and the two acid chloride groups, which enable efficient ring-opening and cross-coupling reactions to construct complex molecular architectures. This compound is essential for researchers and process chemists in the pharmaceutical and agrochemical industries developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those containing cyclopropane motifs for bioactivity enhancement.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where the cyclopropane structure contributes to stability and efficacy.

Quality Control

Our production of 1,2-Cyclopropanedicarbonyl Dichloride, 1-Methyl-, cis- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopy (NMR, IR), to ensure high chemical purity and isomeric consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Store away from strong acids and organic solvents. Recommended long-term storage temperature: 2-8°C.
