Chemical Structure

Xanomeline Impurity 2 CAS 131986-66-8 chemical structure

Description

As a process- or degradation-related impurity, Xanomeline Impurity 2 (CAS 131986-66-8, C15H25N3OS) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Xanomeline Impurity 2 (C15H25N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 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.
