(3R,5R)-Rosuvastatin calcium

Description: (3R,5R)-Rosuvastatin, a potential impurity detected in bulk rosuvastatin formulations, arises as a degradation product through various stresses including acid or base hydrolysis, thermal, photolytic, hydrolytic, oxidative stress, or during storage. This compound is associated with the HMG-CoA reductase inhibitor class to which rosuvastatin belongs. Target: Others. Smiles: C(=C/[C@@H](C[C@H](CC(O)=O)O)O)\C=1C(=NC(N(S(C)(=O)=O)C)=NC1C(C)C)C2=CC=C(F)C=C2.[Ca]
