Chemical Structure
Description
(S)-N-((S)-1-Cyclohexyl-2-((S)-2-(4-(4-fluorobenzoyl)pyridin-2-yl)pyrrolidin-1-yl)-2-oxoethyl)-2-(methylamino)propanamide (C28H35FN4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(S)-N-((S)-1-Cyclohexyl-2-((S)-2-(4-(4-fluorobenzoyl)pyridin-2-yl)pyrrolidin-1-yl)-2-oxoethyl)-2-(methylamino)propanamide (CAS 1005342-47-1) is a high-purity analytical reference standard with the molecular formula C28H35FN4O3 and a molecular weight of 494.60 g/mol.
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.
