BENZENESULFONIC ACID MONOHYDRATE Usage And Synthesis

Uses

Benzenesulfonic acid monohydrate (PhSO₃H. H₂O) can be used as:

• A catalyst to synthesize α,β-unsaturated amides via Pd-catalyzed selective aminocarbonylation of styrenes with nitroarenes.
• A reactant to prepare amino acid benzyl ester salts for the study of gelation in nonpolar solvents.
• A catalyst for the conversion of oxydipropionitrile (nitrile) to di-n-propyl-oxydipropionate (ester).

Uses

Benzenesulfonic Acid Monohydrate is used in the synthesis of HER2/EFGR dual inhibitors in the treatment of cancers and displaying potency towards anti-tumor activity.
