Chemical Structure

Diethylene Glycol Monopentyl Ether CAS 18912-81-7 chemical structure

Description

The occurrence of Diethylene Glycol Monopentyl Ether 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.

CATO supplies Diethylene Glycol Monopentyl Ether (CAS 18912-81-7), a certified reference material (molecular formula C9H20O3, MW 176.25 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Diethylene Glycol Monopentyl Ether is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.25 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.

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.
