1. Pharmaceutical industry: In the key steps of synthesizing chiral drugs (such as β-blockers, antidepressants, antiviral drugs, etc.), d-camphorsulfonic acid is used to resolve chiral amine intermediates.
2. Chiral material science: chiral liquid crystal and display technology, chiral conductive polymers.
3. Nonlinear optical materials: D-camphorsulfonic acid can be used for laser frequency conversion, optical signal modulation and optical data processing.
4. Pesticide synthesis: Many highly efficient and low-toxic pesticides are also chiral, and DCSA can be used for the preparation of their chiral intermediates.
5. Flavors and fine chemicals: D-camphorsulfonic acid used to synthesize chiral molecules with specific aromas.
6. Electrochemistry and Battery Research (Emerging Fields).
1. Strong acidity can serve as a proton source to participate in and catalyze a variety of acid-promoted reactions.
2. Rigid chiral structure provides highly stereoselective recognition and induction capabilities and is an excellent chiral resolving agent and catalyst.
3. Stability and commercial availability: Easy to store and use, and easily available as a commercial reagent.
4. Good crystallinity makes it easy to purify and recover during the separation process.
