Chemical Structure

Pramipexole Impurity 46 CAS 104617-49-4 chemical structure

Description

As a process- or degradation-related impurity, Pramipexole Impurity 46 (CAS 104617-49-4, C7H11N3S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, Pramipexole Impurity 46 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.25 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).

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.
