Diethylene Glycol-d8 CAS 102867-56-1 chemical structure

Description

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.

Diethylene Glycol-d8 (CAS 102867-56-1) is a high-purity analytical reference standard with the molecular formula C4H2D8O3 and a molecular weight of 114.17 g/mol.

Based on its molecular formula C4H2D8O3, Diethylene Glycol-d8 contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 114.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Diethylene Glycol-d8 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.
