The occurrence of Palbociclib Impurity 19 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Palbociclib Impurity 19 (CAS 1941177-47-4), a certified reference material (molecular formula C33H45N7O4, MW 603.75 g/mol) for analytical method development and quality control.
Based on its molecular formula C33H45N7O4, Palbociclib Impurity 19 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 603.75 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).
