METHYLSULFURIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Methylsulfuric acid is a colorless to pale yellow liquid with the chemical formula C₁H₄O₄S, used in various industrial and chemical applications. It is primarily employed as a catalyst in chemical synthesis, in the production of pharmaceuticals and agrochemicals, and as a reagent in laboratory research. Methylsulfuric acid is also used in the formulation of cleaning agents and as an intermediate in the manufacture of other chemicals. Despite its utility, methylsulfuric acid is highly corrosive and poses significant health risks if inhaled, ingested, or absorbed through the skin. Proper handling, storage, and stringent safety measures, including the use of personal protective equipment and adequate ventilation, are essential to minimize risks and ensure safe usage.
