Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.32 g/mol gives Landiolol Impurity 70 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Landiolol Impurity 70 (CAS CATO-C4X-262170) is a certified pharmaceutical impurity reference standard with the molecular formula C12H16O5S and a molecular weight of 272.32 g/mol.
Based on its molecular formula C12H16O5S, Landiolol Impurity 70 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.32 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.
