Chemical Structure

Pasireotide Impurity 17 CAS CATO-C4X-200817 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 2094.41 g/mol gives Pasireotide Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pasireotide Impurity 17 (CAS CATO-C4X-200817) is a certified pharmaceutical impurity reference standard with the molecular formula C116H132N20O18 and a molecular weight of 2094.41 g/mol.

Based on its molecular formula C116H132N20O18, Pasireotide Impurity 17 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 2094.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
