Chemical Structure

Peramivir Impurity 12 CAS 19503-26-5 chemical structure

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.

CATO supplies Peramivir Impurity 12 (CAS 19503-26-5), a pharmacopoeial impurity reference standard (molecular formula C3H5N5HCl, MW 147.57 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Peramivir Impurity 12 (C3H5N5HCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 147.57 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
