Chemical Structure

mPEG-OMs, 95%, average M.W. 1,000 CAS 175172-61-9 chemical structure

Description

As a certified reference material (CRM), mPEG-OMs, 95%, average M.W. 1,000 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.

mPEG-OMs, 95%, average M.W. 1,000 (CAS 175172-61-9) is a high-purity analytical reference standard with the molecular formula C4H10O4S and a molecular weight of 154.18 g/mol.

The molecular framework of mPEG-OMs, 95%, average M.W. 1,000 (C4H10O4S) is characterized by a carbohydrate-derived structure, a sulfone group. 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.
