Chemical Structure

Rivastigmine N-Oxide Impurity HCl CAS 1369779-37-2 chemical structure

Description

The occurrence of Rivastigmine N-Oxide Impurity HCl is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Rivastigmine N-Oxide Impurity HCl (CAS 1369779-37-2) is a certified pharmaceutical impurity reference standard with the molecular formula C14H22N2O3HCl and a molecular weight of 302.80 g/mol.

Structurally, Rivastigmine N-Oxide Impurity HCl (C14H22N2O3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 302.80 g/mol, it falls into the moderately-high-molecular-weight range. 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.

CATO manufactures Rivastigmine N-Oxide Impurity HCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
