P-toluenesulfonic acid monohydrate, CAS 6192-52-5 (This line of electronic-grade chemicals can be customized to meet your specific requirements for metal impurity levels; we welcome custom orders.)

Applications: semiconductor resin curing, photoresist formulation (as a synergistic component of the photoacid generator, PAG), and specialized esterification reactions.

It is strongly acidic and corrosive, readily deliquescent, and must be stored in a tightly sealed container in a dry place. It is readily soluble in water, alcohols, and ethers.
