Chemical Structure
Description
The occurrence of 1,3-Bis(3-glycidyloxypropyl)tetramethyldisiloxane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,3-Bis(3-glycidyloxypropyl)tetramethyldisiloxane (CAS 126-80-7), molecular formula C16H34O5Si2 and molecular weight 362.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,3-Bis(3-glycidyloxypropyl)tetramethyldisiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 362.61 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.
