[2-(2-hydroxyethoxy)ethyl]urea CAS 23194-10-7

Description

Compared with other compounds in its class, the molecular weight of 148.16 g/mol gives [2-(2-hydroxyethoxy)ethyl]urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies [2-(2-hydroxyethoxy)ethyl]urea (CAS 23194-10-7), a certified reference material (molecular formula C5H12N2O3, MW 148.16 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, [2-(2-hydroxyethoxy)ethyl]urea is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.16 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.
