Chemical Structure
Description
As a process- or degradation-related impurity, Landiolol Impurity 58 (CAS CATO-C4X-262158, C44H66N6O13) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Landiolol Impurity 58 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 887.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
