Chemical Structure

Paclitaxel Impurity 60 CAS CATO-C4X-184260 chemical structure

Description

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.

Paclitaxel Impurity 60 (CAS CATO-C4X-184260) is a certified pharmaceutical impurity reference standard with the molecular formula C44H53NO12 and a molecular weight of 787.89 g/mol.

Based on its molecular formula C44H53NO12, Paclitaxel Impurity 60 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 787.89 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.
