Chemical Structure

Azido-PEG11-alcohol CAS 2252392-53-1 chemical structure

Description

Azido-PEG11-alcohol (CAS 2252392-53-1) is a high-purity analytical reference standard with the molecular formula C22H45N3O11 and a molecular weight of 527.61 g/mol.

Based on its molecular formula C22H45N3O11, Azido-PEG11-alcohol 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 527.61 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.
