Description

[(Cyclopropylmethyl)Thio]Acetic Acid CAS NO 959241-50-0 is a specialized organosulfur compound featuring a cyclopropylmethylthio moiety linked to an acetic acid group. This unique structure makes it a valuable synthetic intermediate and building block in advanced organic synthesis. It is primarily required by research and development chemists in the pharmaceutical and agrochemical industries for constructing novel molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a cyclopropane-containing thioether linkage.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides where the cyclopropyl group can enhance biological activity.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands in transition metal catalysis and organocatalysis.
• Material Science Research: Potential monomer or additive in the development of polymers with specific sulfur-containing functionalities.
• Chemical Biology Probes: Useful for synthesizing probes that study enzyme mechanisms or protein interactions involving thioether bonds.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthetic routes.
