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.

(S)-Benzyl 2-azetidinone-4-carboxylate 72776-05-7 Benzyl (S)-4-oxo-2-azetidinecarboxylate EBD29054 (CAS 72776-05-7) is a high-purity analytical reference standard with the molecular formula C11H17NO3 and a molecular weight of 211.26 g/mol.

The molecular framework of (S)-Benzyl 2-azetidinone-4-carboxylate 72776-05-7 Benzyl (S)-4-oxo-2-azetidinecarboxylate EBD29054 (C11H17NO3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
