Chemical Structure

Triethylene Glycol Dimethyl Ether CAS 112-49-2 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.

Triethylene Glycol Dimethyl Ether (CAS 112-49-2), molecular formula C8H18O4 and molecular weight 178.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Triethylene Glycol Dimethyl Ether is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
