Chemical Structure
Description
Desmopressin Impurity 20 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
Desmopressin Impurity 20 (CAS CATO-C4X-221520) is a certified pharmaceutical impurity reference standard with the molecular formula N/A and a molecular weight of N/A g/mol.
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.
