Chemical Structure

Rosuvastatin Impurity 64 CAS 124655-09-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 260.33 g/mol gives Rosuvastatin Impurity 64 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Rosuvastatin Impurity 64 (CAS 124655-09-0, C13H24O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Rosuvastatin Impurity 64 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
