Chemical Structure

(2S,3R)-Methyl 2-amino-3-(tert-butoxy)butanoate CAS 24205-25-2 chemical structure

Description

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.

CATO supplies (2S,3R)-Methyl 2-amino-3-(tert-butoxy)butanoate (CAS 24205-25-2), a certified reference material (molecular formula C9H19NO3, MW 189.25 g/mol) for analytical method development and quality control.

The molecular framework of (2S,3R)-Methyl 2-amino-3-(tert-butoxy)butanoate (C9H19NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
