Chemical Structure

Indacaterol Impurity 25 CAS 1207760-24-4 chemical structure

Description

The occurrence of Indacaterol Impurity 25 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Indacaterol Impurity 25 (CAS 1207760-24-4) is a certified pharmaceutical impurity reference standard with the molecular formula C49H49N3O6 and a molecular weight of 775.93 g/mol.

Based on its molecular formula C49H49N3O6, Indacaterol Impurity 25 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 775.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
