CATO supplies 8-Ethyl-2-[[4-(4-methylpiperazin-1-yl)phenyl]amino]-8H-pyrido[2,3-d]pyrimidin-7-one (CAS 211245-14-6), a certified reference material (molecular formula C20H24N6O, MW 364.44 g/mol) for analytical method development and quality control.
Structurally, 8-Ethyl-2-[[4-(4-methylpiperazin-1-yl)phenyl]amino]-8H-pyrido[2,3-d]pyrimidin-7-one (C20H24N6O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 364.44 g/mol, it falls into the moderately-high-molecular-weight range. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
