Chemical Structure

m-PEG5-SH CAS 524030-00-0 chemical structure

Description

m-PEG5-SH (CAS 524030-00-0) is a high-purity analytical reference standard with the molecular formula C11H24O5S and a molecular weight of 268.37 g/mol.

The molecular framework of m-PEG5-SH (C11H24O5S) 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.

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.

As a certified reference material (CRM), m-PEG5-SH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
