Chemical Structure

Ms-PEG7-Ms CAS 109789-41-5 chemical structure

Description

The occurrence of Ms-PEG7-Ms 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.

Ms-PEG7-Ms (CAS 109789-41-5), molecular formula C16H34O12S2 and molecular weight 482.56 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H34O12S2, Ms-PEG7-Ms contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 482.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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), Ms-PEG7-Ms 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.
