Chemical Structure

2-(Prop-2-yn-1-ylamino)ethan-1-ol CAS 28123-89-9 chemical structure

Description

2-(Prop-2-yn-1-ylamino)ethan-1-ol (CAS 28123-89-9) is a high-purity analytical reference standard with the molecular formula C5H9NO and a molecular weight of 99.13 g/mol.

Based on its molecular formula C5H9NO, 2-(Prop-2-yn-1-ylamino)ethan-1-ol contains 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 99.13 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.
