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, Adenosine Impurity 13 (CAS 49540-14-9, C5H10O4S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C5H10O4S, Adenosine Impurity 13 contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 166.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
