D,L-Camphorsulfonic Acid

Camphorsulfonic acid (CSA) is a derivative of camphor, widely used in medicine, light industry and cosmetic industry and is an important organic synthesis intermediate.

It is an organosulfur compound. Like typical sulfonic acids. Camphorsulfonic acid (CSA) is a relatively strong acid that is a colorless solid at room temperature. It is soluble in water and a wide variety of organic substances.

Its application is mainly focused on chiral asymmetric synthesis.

In organic sythesis, Camphorsulfonic acid (CSA) and its derivatives can be used as resolving agents for chiral amines and other cations. The synthesis of osanetant was an example of this. 3-bromocamphor-8-sulfonic acid was used in the synthesis of enantiopure devazepide. Furthermore Camphorsulfonic acid (CSA) is used in some pharmaceutical formulations, where it is referred to as camsilate or camsylate including trimetaphan camsilate and lanabecestat camsylate.

Shelf Life

Under proper storage conditions, the shelf life is 12 months.
