Chemical Structure

Rasagiline Impurity 43 CAS CATO-C4X-191343 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rasagiline Impurity 43.

Rasagiline Impurity 43 (CAS CATO-C4X-191343) is a certified pharmaceutical impurity reference standard with the molecular formula C12H14N2 and a molecular weight of 186.25 g/mol.

The molecular framework of Rasagiline Impurity 43 (C12H14N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
