Simvastatin EP Impurity M CAS 864357-87-9 chemical structure

Description

CATO supplies Simvastatin EP Impurity M (CAS 864357-87-9), a pharmacopoeial impurity reference standard (molecular formula C27H44O6, MW 464.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Simvastatin EP Impurity M (C27H44O6) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 464.63 g/mol, it falls into the moderately-high-molecular-weight range. 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
