Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 448.55 g/mol gives 6-Carboxy-delta,5’,4’,5,6-Simvastatin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Carboxy-delta,5’,4’,5,6-Simvastatin (CAS 125206-31-7), molecular formula C25H36O7 and molecular weight 448.55 g/mol, is a CATO reference standard with documented purity and traceability.
6-Carboxy-delta,5’,4’,5,6-Simvastatin (C25H36O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
