Chemical Structure

DMG-PEG 2000 CAS 1397695-86-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 2509.20 g/mol gives DMG-PEG 2000 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

DMG-PEG 2000 (CAS 1397695-86-1) is a high-purity analytical reference standard with the molecular formula C122H242O50 and a molecular weight of 2509.20 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, DMG-PEG 2000 is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2509.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

CATO manufactures DMG-PEG 2000 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
