Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.78 g/mol gives Memantine-d3 HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Memantine-d3 HCl (CAS 1329802-06-3) is a high-purity analytical reference standard with the molecular formula C12H18D3NHCl and a molecular weight of 218.78 g/mol.
Structurally, Memantine-d3 HCl (C12H18D3NHCl) contains deuterium isotope labeling, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 218.78 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
