Description

2-Yl Trifluoromethanesulfonate (CAS NO 145326-64-3) is a high-value organotriflate reagent and versatile synthetic building block. Its primary value lies in its exceptional reactivity as an alkylating agent and a precursor for introducing functional groups in complex molecular architectures. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors, enabling critical carbon-carbon and carbon-heteroatom bond-forming reactions.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for introducing alkyl or functionalized alkyl groups.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators requiring specific alkyl motifs.
• Cross-Coupling Reactions: Serves as an effective electrophile in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Negishi, Stille) for constructing complex organic molecules.
• Polymer & Material Science: Monomer or modifier in the development of specialty polymers, liquid crystals, and functional materials.
• Organic Synthesis & Methodology Development: A valuable reagent for academic and industrial R&D in developing new synthetic methodologies and creating molecular libraries.
• Ligand & Catalyst Preparation: Intermediate in the synthesis of specialized ligands and organometallic catalysts.
