Methane sulfonic acid 70% solution is used virtually in all electronic applications involving tin or tin-alloy plating from non fluoborate systems. It replaces phosphoric acid in detergent formulations, thereby helping to avoid environmental phosphate pollution. It is used in the preparation of polyaniline/graphene nanocomposites, which enhances its thermal and electrical properties. It is utilized for electropolishing of aluminum as well as in electroplating of noble metals like gold, platinum, palladium and their alloys.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
