Ethyl 2-(ethylamino)butanoate CAS 874525-99-2

Description

Compared with other compounds in its class, the molecular weight of 159.23 g/mol gives Ethyl 2-(ethylamino)butanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-(ethylamino)butanoate (CAS 874525-99-2), molecular formula C8H17NO2 and molecular weight 159.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ethyl 2-(ethylamino)butanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
