(2S,4R)-1-[(2S)-2-(7-aminoheptanoylamino)-3,3-dimethyl-butanoyl]-4-hydroxy-N-[[4-(4-methylthiazol-5-yl)phenyl]methyl]pyrrolidine-2-carboxamide (CAS 2306389-03-5), molecular formula C29H53N5O4S and molecular weight 567.83 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C29H53N5O4S, (2S,4R)-1-[(2S)-2-(7-aminoheptanoylamino)-3,3-dimethyl-butanoyl]-4-hydroxy-N-[[4-(4-methylthiazol-5-yl)phenyl]methyl]pyrrolidine-2-carboxamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 567.83 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).
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.
