Description

Cyclobutene, 1,2-Dichloro-3,3-Difluoro- (8Ci,9Ci) is a halogenated cyclobutene derivative, a versatile and reactive building block in advanced organic synthesis. Its unique structure, featuring both chlorine and fluorine substituents on a strained four-membered ring, makes it a valuable precursor for creating complex fluorinated molecules. This compound is primarily utilized by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and specialty materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of novel fluorinated drug candidates, particularly for central nervous system (CNS) and anti-infective therapies.
• Agrochemical Synthesis: Used in the creation of advanced herbicides, pesticides, and fungicides where the introduction of fluorine atoms enhances biological activity and environmental stability.
• Material Science Precursor: Acts as a monomer or cross-linking agent in the development of specialty polymers and coatings with unique thermal or chemical resistance properties.
• Organic Synthesis Building Block: Employed in [3+2] cycloadditions and ring-opening reactions to construct complex, polycyclic, and fluorinated organic frameworks in academic and industrial R&D.
• Liquid Crystal & Electronic Chemical Intermediate: Utilized in the synthesis of fluorinated components for liquid crystal displays (LCDs) and other electronic materials.

Quality Control

Every batch of Cyclobutene, 1,2-Dichloro-3,3-Difluoro- is produced and analyzed under strict quality management protocols. Our products undergo rigorous quality testing, including chromatographic purity analysis and identity confirmation, to ensure consistency and compliance with research and development standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed and at a consistent, cool temperature (recommended 2-8°C or as specified on the label) to maintain stability and prevent loss.
