Chemical Structure

Regadenoson Impurity N21 CAS 80370-42-9 chemical structure

Description

As a process- or degradation-related impurity, Regadenoson Impurity N21 (CAS 80370-42-9, C6H8O4) 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, Regadenoson Impurity N21 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
