Chemical Structure
Description
Structurally, Methyl (2S)-2-{[(benzyloxy)carbonyl]amino}-5-{[(tert-butoxy)carbonyl]amino}pentanoate (C19H28N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 380.44 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Methyl (2S)-2-{[(benzyloxy)carbonyl]amino}-5-{[(tert-butoxy)carbonyl]amino}pentanoate (CAS 32393-52-5) is a high-purity analytical reference standard with the molecular formula C19H28N2O6 and a molecular weight of 380.44 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.
