Chemical Structure
Description
Based on its molecular formula C25H38O6, 5(S)-Hydroxy Simvastatin contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 434.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5(S)-Hydroxy Simvastatin (CAS 149949-05-3) is a high-purity analytical reference standard with the molecular formula C25H38O6 and a molecular weight of 434.57 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
