Aminooxy-PEG3-C2-thiol CAS 1200365-63-4 chemical structure

Description

CATO supplies Aminooxy-PEG3-C2-thiol (CAS 1200365-63-4), a certified reference material (molecular formula C8H19NO4S, MW 225.31 g/mol) for analytical method development and quality control.

Aminooxy-PEG3-C2-thiol (C8H19NO4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
