Chemical Structure

Memantine Impurity N1(Mixture of Diastereomers) CAS 16207-81-1 chemical structure

Description

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.

CATO supplies Memantine Impurity N1(Mixture of Diastereomers) (CAS 16207-81-1), a pharmacopoeial impurity reference standard (molecular formula C12H20, MW 164.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H20, Memantine Impurity N1(Mixture of Diastereomers) contains an organic framework; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
