Chemical Structure

2-tert-Butoxycarbonylamino-3-oxo-3-phenyl-propionic acid ethyl ester CAS 151870-52-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 307.34 g/mol gives 2-tert-Butoxycarbonylamino-3-oxo-3-phenyl-propionic acid ethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-tert-Butoxycarbonylamino-3-oxo-3-phenyl-propionic acid ethyl ester (CAS 151870-52-9), a certified reference material (molecular formula C16H21NO5, MW 307.34 g/mol) for analytical method development and quality control.

The molecular framework of 2-tert-Butoxycarbonylamino-3-oxo-3-phenyl-propionic acid ethyl ester (C16H21NO5) is characterized by a flavonoid core, 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 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.
