Chemical Structure

Propargyl-PEG6-SH CAS 1422540-91-7 chemical structure

Description

The molecular framework of Propargyl-PEG6-SH (C15H28O6S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Propargyl-PEG6-SH (CAS 1422540-91-7) is a high-purity analytical reference standard with the molecular formula C15H28O6S and a molecular weight of 336.44 g/mol.

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.
