Caspofungin Impurity A02-2 Acetate CAS 1404083-47-1(Free Base)

Description

Compared with other compounds in its class, the molecular weight of 1167.37 g/mol gives Caspofungin Impurity A02-2 Acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Caspofungin Impurity A02-2 Acetate (CAS 1404083-47-1(Free Base), C52H86N10O16x·C2H4O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C52H86N10O16x·C2H4O2, Caspofungin Impurity A02-2 Acetate 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 1167.37 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.
