Chemical Structure

Methyl 2-(aminooxy)propanoate CAS 91666-48-7 chemical structure

Description

Methyl 2-(aminooxy)propanoate (CAS 91666-48-7), molecular formula C4H9NO3 and molecular weight 119.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H9NO3, Methyl 2-(aminooxy)propanoate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 119.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
