Chemical Structure

N-(2-Hydroxyethyl)stearamide CAS 111-57-9 chemical structure

Description

N-(2-Hydroxyethyl)stearamide (CAS 111-57-9) is a high-purity analytical reference standard with the molecular formula C20H41NO2 and a molecular weight of 327.55 g/mol.

Based on its molecular formula C20H41NO2, N-(2-Hydroxyethyl)stearamide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 327.55 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.
