Chemical Structure

Molnupiravir Impurity 1 CAS 2591381-21-2 chemical structure

Description

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.

As a process- or degradation-related impurity, Molnupiravir Impurity 1 (CAS 2591381-21-2, C9H16O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Molnupiravir Impurity 1 (C9H16O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
