Application

(+)-Camphor-10-sulfonic acid may be used as a starting material to synthesize 10-iodocamphor. (±)-S-methyl-S-phenylsulfoximine can be resolved using it as a chiral resolving agent to form the (-)-form in high enantiomeric purity. Polyaniline (PAni) doped with (+)-camphor-10-sulfonic acid forms electrically conductive polymer nanofibers, which are excellent ammonia gas sensors.

Other Notes

Reagent used for the resolution of bases; use as mobile phase additive for LC separations; Reagent used for crystallization-induced asymmetric transformations
