(1R)-(-)-10-Camphorsulfonic acid CAS No.:35963-20-3
Pharmaceutical Materials 2025-03-03
(1R)-(-)-10-Camphorsulfonic acid (CAS No.: 35963-20-3), commonly referred to as L-(-)-camphorsulfonic acid, is a versatile organic compound with a molecular formula of C10H16O4S and a molecular weight of 232.3 g/mol. It exists as a white or almost white crystalline powder and is notable for its hygroscopic nature, making it prone to moisture absorption in humid environments. This compound has a melting point ranging from 193°C to 195°C (decomposes) and exhibits limited solubility in ethers, with slight solubility in acetic acid and ethyl acetate. It is widely used as an acid catalyst in organic synthesis, particularly in reactions involving hydroxyl groups, and as a chiral auxiliary agent due to its unique spatial structure, facilitating stereoselective reactions. Additionally, it serves as an intermediate in pharmaceuticals and for resolving racemic mixtures.
Usage： Organic synthesis intermediate, resolution agent.
Packaging and Shipping： 25KG/drum as per buyer requirement.
Storage: Stored in a dry and ventilated warehouse; keep away from sunshine; avoid fire; avoid moisture.
