Silver methanesulfonate（Cat No.:L045258）is an organometallic salt composed of a silver cation and a methanesulfonate (mesylate) anion. It is used as a mild, silver-based reagent in organic synthesis, particularly for promoting halide abstraction, facilitating carbocation formation, or enabling oxidative coupling reactions. Its mesylate component imparts good solubility in polar solvents, while the silver ion can participate in coordination chemistry and redox transformations. Silver methanesulfonate is valued in the development of pharmaceuticals and fine chemicals, offering controlled reactivity and compatibility with sensitive functional groups under mild reaction conditions.
