Chemical Structure

Azelastine Impurity 35 CAS CATO-C4X-139635 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 179.69 g/mol gives Azelastine Impurity 35 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Azelastine Impurity 35 (CAS CATO-C4X-139635) is a certified pharmaceutical impurity reference standard with the molecular formula C7H17N3HCl and a molecular weight of 179.69 g/mol.

Azelastine Impurity 35 (C7H17N3HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
