Chemical Structure
Description
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.
Ethyl (S)-2-(3-Amino-2-oxo-1-piperidinyl)acetate Hydrochloride (CAS 937057-79-9) is a high-purity analytical reference standard with the molecular formula C9H16N2O3HCl and a molecular weight of 236.70 g/mol.
The molecular framework of Ethyl (S)-2-(3-Amino-2-oxo-1-piperidinyl)acetate Hydrochloride (C9H16N2O3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
