Chemical Structure

Ivabradine Impurity 25 HCl CAS 1132079-01-6 chemical structure

Description

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.

Ivabradine Impurity 25 HCl (CAS 1132079-01-6) is a certified pharmaceutical impurity reference standard with the molecular formula C11H15NO2 and a molecular weight of 193.24 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ivabradine Impurity 25 HCl is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
