Chemical Structure
Description
(S)-Methyl 2-((S)-2-((S)-2-aminopropanamido)propanamido)propanoate hydrochloride (CAS 41036-27-5) is a high-purity analytical reference standard with the molecular formula C10H19N3O4C2H4O2 and a molecular weight of 305.33 g/mol.
The molecular framework of (S)-Methyl 2-((S)-2-((S)-2-aminopropanamido)propanamido)propanoate hydrochloride (C10H19N3O4C2H4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
