Key value for chemical safety assessment
Additional information
Trifluoromethanesulfonic acid belongs to the class of superacids, which are defined as stronger than 100% sulfuric acid. The standard way to classify acid strengths regarding their ionic dissociation in water is not applicable to superacids since they are all fully dissociated in aqueous solution (pKa<0).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
