Description
4-Amino-6-[[(1S)-1-[8-(1,6-dihydro-1-methyl-6-oxo-3-pyridinyl)-1,2-dihydro-2-(1-methylethyl)-1-oxo-3-isoquinolinyl]ethyl]amino]-5-pyrimidinecarbonitrile (CAS 1425043-73-7), molecular formula C25H25N7O2 and molecular weight 455.51 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-6-[[(1S)-1-[8-(1,6-dihydro-1-methyl-6-oxo-3-pyridinyl)-1,2-dihydro-2-(1-methylethyl)-1-oxo-3-isoquinolinyl]ethyl]amino]-5-pyrimidinecarbonitrile (C25H25N7O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
