Chemical Structure

3-(Ethylamino)-3-oxopropanoic acid CAS 773098-59-2 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.

3-(Ethylamino)-3-oxopropanoic acid (CAS 773098-59-2), molecular formula C5H9NO3 and molecular weight 131.13 g/mol, is a CATO reference standard with documented purity and traceability.

3-(Ethylamino)-3-oxopropanoic acid (C5H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
