Chemical Structure

Eperisone Impurity 50 CAS 1160227-93-9 chemical structure

Description

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.

As a process- or degradation-related impurity, Eperisone Impurity 50 (CAS 1160227-93-9, C17H27NO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Eperisone Impurity 50 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
