Chemical Structure
Description
Tert-butyl (L-alanyl-L-prolyl)((S)-1-((benzoyloxy)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (CAS 157135-53-0) is a high-purity analytical reference standard with the molecular formula C29H36N4O7 and a molecular weight of 552.62 g/mol.
Structurally, Tert-butyl (L-alanyl-L-prolyl)((S)-1-((benzoyloxy)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (C29H36N4O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 552.62 g/mol, it falls into the moderately-high-molecular-weight range. 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.
