Chemical Structure

1,4-Dioxane CAS 123-91-1 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,4-Dioxane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 88.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

CATO supplies 1,4-Dioxane (CAS 123-91-1), a certified reference material (molecular formula C4H8O2, MW 88.11 g/mol) for analytical method development and quality control.

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.
