Chemical Structure

HS-PEG11-CH2CH2N3 CAS 2148986-08-5 chemical structure

Description

The occurrence of HS-PEG11-CH2CH2N3 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies HS-PEG11-CH2CH2N3 (CAS 2148986-08-5), a certified reference material (molecular formula C24H49N3O11S, MW 587.72 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H49N3O11S, HS-PEG11-CH2CH2N3 contains an amide group, a sulfone 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 587.72 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.
