Chemical Structure

Memantine impurity 47 CAS 90812-21-8 chemical structure

Description

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.

CATO supplies Memantine impurity 47 (CAS 90812-21-8), a pharmacopoeial impurity reference standard (molecular formula C10H16ClNHCl, MW 222.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C10H16ClNHCl, Memantine impurity 47 contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 222.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
