Description

Cyclopropanethiol CAS NO 6863-32-7 is a highly reactive organosulfur compound characterized by its strained three-membered cyclopropane ring. This unique structure makes it a valuable and versatile building block in advanced organic synthesis, particularly for introducing the cyclopropylthio moiety into complex molecules. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for the development of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) with cyclopropane-containing structures, potentially for antiviral, antibacterial, or central nervous system (CNS) drugs.
• Agrochemical Synthesis: Used as a building block for creating novel pesticides, herbicides, and fungicides where the cyclopropylthio group can enhance biological activity and stability.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands and organocatalysts used in asymmetric synthesis and transition metal catalysis.
• Material Science Research: Employed in the development of novel polymers, functionalized surfaces, and advanced materials with specific sulfur-based properties.
• Flavor & Fragrance Industry: Potential intermediate for synthesizing sulfur-containing aroma compounds, contributing to complex flavor profiles.
• Organic Synthesis Reagent: A versatile reagent for thioetherification reactions, nucleophilic substitutions, and cycloadditions in academic and industrial R&D laboratories.

Quality Control

Our Cyclopropanethiol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing purity, assay, and impurity profiles to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this product should be stored under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. Keep the container in a cool, well-ventilated place away from heat, sparks, and open flames. Use appropriate safety measures to prevent moisture ingress and oxidation.
