Chemical Structure

Acid-PEG8-S-S-PEG8-acid CAS 873013-93-5 chemical structure

Description

The occurrence of Acid-PEG8-S-S-PEG8-acid is closely related to 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.

Acid-PEG8-S-S-PEG8-acid (CAS 873013-93-5) is a high-purity analytical reference standard with the molecular formula C38H74O20S2 and a molecular weight of 915.11 g/mol.

The molecular framework of Acid-PEG8-S-S-PEG8-acid (C38H74O20S2) 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), Acid-PEG8-S-S-PEG8-acid 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.
