Description
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.
Vazegepant impurity 36 (CAS 3019989-24-0) is a certified pharmaceutical impurity reference standard with the molecular formula C40H41N7O4 and a molecular weight of 683.80 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Vazegepant impurity 36 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 683.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
