Chemical Structure

Triethylene glycol monoethyl ether CAS 112-50-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 178.23 g/mol gives Triethylene glycol monoethyl ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Triethylene glycol monoethyl ether (CAS 112-50-5), a certified reference material (molecular formula C8H18O4, MW 178.23 g/mol) for analytical method development and quality control.

Structurally, Triethylene glycol monoethyl ether (C8H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 178.23 g/mol, it falls into the medium-molecular-weight range.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
