Chemical Structure

Vinblastine impurity 7 CAS CATO-C4X-19847 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 826.97 g/mol gives Vinblastine impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Vinblastine impurity 7 (CAS CATO-C4X-19847) is a certified pharmaceutical impurity reference standard with the molecular formula C46H58N4O10 and a molecular weight of 826.97 g/mol.

Based on its molecular formula C46H58N4O10, Vinblastine impurity 7 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 826.97 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
