Description

Cyclopropane, (1-Chloroethenyl)- CAS NO 24154-06-1 is a specialized halogenated cyclopropane derivative, a key building block in advanced organic synthesis. Its reactive vinyl chloride moiety fused to a strained three-membered ring makes it a valuable precursor for constructing complex molecular architectures. This compound is essential for research chemists and process development scientists in the pharmaceutical and agrochemical industries, where it is used to introduce the cyclopropyl group—a motif known for modulating biological activity, metabolic stability, and physicochemical properties.

Application

• Pharmaceutical Intermediate: Serves as a critical synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing cyclopropane rings for enhanced potency and stability.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, where the cyclopropyl group can improve efficacy and environmental profile.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of specialized polymers with unique thermal or mechanical properties.
• Organic Synthesis Building Block: Employed in [2+1] cycloadditions, ring-opening reactions, and as a versatile electrophile or radical acceptor in C-C bond-forming reactions.
• Ligand and Catalyst Development: Utilized to create novel cyclopropane-containing ligands for asymmetric catalysis and metal-organic frameworks (MOFs).
• Flavor and Fragrance Industry: Potential intermediate for synthesizing specific aroma chemicals with unique olfactory characteristics.

Quality Control

Every batch of Cyclopropane, (1-Chloroethenyl)- is produced and analyzed under strict quality management protocols. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing purity, identity, and impurity profiles. We support custom synthesis and can tailor specifications to meet the stringent requirements of cGMP, ICH guidelines, and other relevant regulatory frameworks for advanced intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, open flames, and strong acids or organic solvents. Due to its light-sensitive nature and reactivity, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep the container tightly sealed to prevent moisture ingress and volatilization.
