Selectfluor
Selectfluor (CAS: 140681-55-6) is a stable, crystalline electrophilic fluorinating reagent that delivers fluorine to a wide range of organic substrates under mild conditions. It replaces hazardous elemental fluorine and chlorine monofluoride in many syntheses, offering safe bench-scale handling as a free-flowing powder that can be stored without pressure equipment or special facilities. The reagent is widely used to fluorinate enol ethers, silyl enol ethers, sulfides, and electron-rich aromatics, supporting the production of fluorinated pharmaceuticals, agrochemicals, and fine chemicals. Reactions typically proceed at ambient temperature in common solvents such as acetonitrile, giving clean conversion and straightforward work-up. Customers value its high selectivity, predictable reactivity, long shelf life, and the process-safety benefits it brings to fluorination chemistry.
• Pharmaceutical synthesis: direct fluorination of drug intermediates to improve potency, selectivity, and metabolic stability, supporting modern medicinal chemistry programs from discovery to production.
• Agrochemicals: introduces fluorine into herbicide, insecticide, and fungicide building blocks to enhance biological performance and field durability of crop-protection products.
• Fine chemicals: regioselective fluorination of enol ethers, olefins, sulfides, and electron-rich rings used in fragrance, dye, and specialty synthesis.
• Process safety: a mild, handling-friendly alternative to elemental fluorine and aggressive fluorinating agents, simplifying plant design, storage, and operator protection.
