Description

Trifluoromethylfluoromethanesulfide is a specialized organofluorine and organosulfur compound with the CAS number 99485-66-2. This high-value intermediate is critical for introducing the trifluoromethylthio (SCF₃) group, a highly lipophilic and electron-withdrawing moiety that significantly alters the physicochemical properties of target molecules. It is primarily sought after by research and development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) with enhanced metabolic stability and membrane permeability.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides where the SCF₃ group improves bioactivity and environmental persistence.
• Material Science Research: Employed in the creation of novel fluorinated polymers and specialty chemicals with unique surface properties and chemical resistance.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands used in catalysis and molecular recognition.
• Life Science Reagents: Utilized in the preparation of biochemical probes and labeling reagents for diagnostic and research applications.
