trans-Benzyl (S)-4-(((S)-1-amino-1-oxo-3-phenylpropan-2-yl)(methyl)amino)-4-oxo-3-((2S,3S)-3-propylpyrrolidine-2-carboxamido)butanoate hydrochloride (CAS 134676-16-7) is a high-purity analytical reference standard with the molecular formula C29H38N4O5HCl and a molecular weight of 559.10 g/mol.
trans-Benzyl (S)-4-(((S)-1-amino-1-oxo-3-phenylpropan-2-yl)(methyl)amino)-4-oxo-3-((2S,3S)-3-propylpyrrolidine-2-carboxamido)butanoate hydrochloride (C29H38N4O5HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
