Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Oseltamivir Impurity 151 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.60 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.
CATO supplies Oseltamivir Impurity 151 (CAS 651324-06-0), a pharmacopoeial impurity reference standard (molecular formula C24H42N2O3, MW 406.60 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
