Description

2,3,4,5,6-Pentafluorobiphenyl CAS NO 784-14-5 is a highly fluorinated aromatic compound valued for its unique electronic properties and chemical stability. This specialty chemical serves as a critical building block and intermediate in advanced material science and fine chemical synthesis. It is primarily sought after by R&D laboratories and manufacturers in the pharmaceutical, agrochemical, and liquid crystal industries for developing novel compounds with enhanced performance characteristics.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated aromatic systems to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Acts as a key precursor for developing modern pesticides and herbicides, where the pentafluorophenyl group can contribute to product efficacy and environmental persistence.
• Liquid Crystal Materials: Employed in the production of fluorinated liquid crystals for high-performance displays (LCDs) due to its ability to influence dielectric anisotropy and viscosity.
• Organic Electronics: Serves as a building block for electron-transport materials, semiconductors, and other components in organic light-emitting diodes (OLEDs) and photovoltaic cells.
• Chemical Research & Development: Utilized as a standard or reagent in cross-coupling reactions (e.g., Suzuki, Stille) and as a model compound in studies of fluorinated aromatics.
• Polymer Modification: Can be incorporated into polymer chains to create specialty plastics with improved chemical resistance, thermal stability, or surface properties.
