Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 145.20 g/mol gives (S)-Ethyl 2-amino-2-methylbutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-Ethyl 2-amino-2-methylbutanoate (CAS 13893-46-4), a certified reference material (molecular formula C7H15NO2, MW 145.20 g/mol) for analytical method development and quality control.
(S)-Ethyl 2-amino-2-methylbutanoate (C7H15NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
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.
