Description

Silver Tetrafluoroborate (AgBF₄) is a highly reactive inorganic compound widely used in synthetic chemistry and materials science. This white to off-white crystalline solid exhibits excellent solubility in polar organic solvents, making it a versatile reagent for electrophilic reactions, catalysis, and electrochemical applications. With a molecular weight of 194.67 g/mol and CAS number 14104-20-2, it is supplied as a high-purity (>98%) material suitable for sensitive research applications. Silver tetrafluoroborate is hygroscopic and must be stored under inert conditions to maintain stability. Its strong Lewis acid properties make it particularly valuable for halogen abstraction, silver(I)-mediated couplings, and as a precursor for silver nanoparticle synthesis.
