| Use Pattern |
| Camphor-10-sulfonic acid (β) (CSA) is extensively used as an acid catalyst. • It can be used in a catalytic amount to protect hydroxyl groups as tetrahydropyranyl (THP) ethers using dihydropyran. • It also catalyzes the protection of ketones as ketals. • It is a useful catalyst for the intramolecular ring opening of epoxides. • CSA can also be used to catalyze nucleophile-promoted alkyne-iminium cyclization in the total synthesis of pumiliotoxin A. |
| starting material for manufacturing a composite catalyst suitable for making polyethylene terephthalate resin |
| Resolving agent |
| Camphorsulfonic acid is a organosulphur compound. |
