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.
Tirzepatide Impurity 47 (CAS CATO-C4X-324047) is a certified pharmaceutical impurity reference standard with the molecular formula N/A and a molecular weight of N/A g/mol.
Tirzepatide Impurity 47 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).
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.
| Purity | ≥90% |
| Storage | Store at 2-8°C |
| Solubility (reference) | Freely soluble in water |
| Stability | Stable under recommended storage conditions |
