Ranitidine Impurity N6 CAS 1197-40-6

Description

Compared with other compounds in its class, the molecular weight of 148.16 g/mol gives Ranitidine Impurity N6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ranitidine Impurity N6 (CAS 1197-40-6), a pharmacopoeial impurity reference standard (molecular formula C9H8O2, MW 148.16 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ranitidine Impurity N6 (C9H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 148.16 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).

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.
