2-Ethyl-2-isobutyramidobutanoic acid CAS 1421263-51-5

Description

Compared with other compounds in its class, the molecular weight of 201.26 g/mol gives 2-Ethyl-2-isobutyramidobutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Ethyl-2-isobutyramidobutanoic acid (CAS 1421263-51-5), a certified reference material (molecular formula C10H19NO3, MW 201.26 g/mol) for analytical method development and quality control.

Structurally, 2-Ethyl-2-isobutyramidobutanoic acid (C10H19NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 201.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
