L-(-)-Camphorsulfonic acid is widely used as a chiral resolving agent in the pharmaceutical industry to separate enantiomers of racemic mixtures, ensuring the production of optically pure compounds. It is also employed as a catalyst in organic synthesis, particularly in asymmetric reactions, due to its ability to induce chirality and enhance reaction efficiency. In polymer chemistry, it serves as a dopant for conductive polymers like polyaniline, improving their electrical conductivity and stability. Additionally, it finds application in the preparation of electrolytes for fuel cells and batteries, where it enhances ion transport and performance. Its use in analytical chemistry as a reference standard for polarimetric studies further highlights its versatility.
