Compared with other compounds in its class, the molecular weight of 171.24 g/mol gives Argatroban Impurity N1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Argatroban Impurity N1 (CAS 74863-85-7) is a certified pharmaceutical impurity reference standard with the molecular formula C9H17NO2 and a molecular weight of 171.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Argatroban Impurity N1 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.24 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.
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.
