Chemical Structure
Description
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.
CATO supplies methyl (S)-(1-((4-(3-(3-((tert-Butoxycarbonyl)amino)-5-chloro-2-fluorophenyl)-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-yl)amino)propan-2-yl)carbamate (CAS 1269440-77-8), a certified reference material (molecular formula C26H33ClFN7O4, MW 562.04 g/mol) for analytical method development and quality control.
Based on its molecular formula C26H33ClFN7O4, methyl (S)-(1-((4-(3-(3-((tert-Butoxycarbonyl)amino)-5-chloro-2-fluorophenyl)-1-isopropyl-1H-pyrazol-4-yl)pyrimidin-2-yl)amino)propan-2-yl)carbamate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 562.04 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.
