Description
[4-[[5-Fluoro-4-[2-methyl-1-(1-methylethyl)-1H-imidazol-5-ly]-2-pyrimidinyl]amino]phenyl][(3S)-3-(methylamino)-1-pyrrolidinyl]methanone (CAS 924641-59-8), molecular formula C23H28FN7O and molecular weight 437.51 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H28FN7O, [4-[[5-Fluoro-4-[2-methyl-1-(1-methylethyl)-1H-imidazol-5-ly]-2-pyrimidinyl]amino]phenyl][(3S)-3-(methylamino)-1-pyrrolidinyl]methanone contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 437.51 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).
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.
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.
