Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 552.64 g/mol gives Ribociclib succinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ribociclib succinate (CAS 1374639-75-4) is a high-purity analytical reference standard with the molecular formula C23H30N8OC4H6O4 and a molecular weight of 552.64 g/mol.
Based on its molecular formula C23H30N8OC4H6O4, Ribociclib succinate contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 552.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
