Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 467.60 g/mol gives Cabergoline Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cabergoline Impurity 8 (CAS CATO-C4X-27748), a pharmacopoeial impurity reference standard (molecular formula C26H37N5O3, MW 467.60 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Cabergoline Impurity 8 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 467.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
