Chemical Structure

Rasagiline impurity 59 CAS CATO-C4X-191359 chemical structure

Description

The molecular framework of Rasagiline impurity 59 (C12H12O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a process- or degradation-related impurity, Rasagiline impurity 59 (CAS CATO-C4X-191359, C12H12O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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.
