Explanation:
Detailed explanation-1: -Camphor is practically insoluble in water but soluble in alcohol, ether, chloroform, and other solvents.
Detailed explanation-2: -(1S)-(–)-Camphor is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of (1S)-(–)-camphor in ethanol and DMF is approximately 30 mg/ml and approximately 20 mg/ml in DMSO. (1S)-(–)-Camphor is sparingly soluble in aqueous buffers.
