Chemical Structure

(4S)-4-Ethyl-1,3-dioxolan-2-one CAS 90970-72-2 chemical structure

Description

CATO supplies (4S)-4-Ethyl-1,3-dioxolan-2-one (CAS 90970-72-2), a certified reference material (molecular formula C5H8O3, MW 116.12 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (4S)-4-Ethyl-1,3-dioxolan-2-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 116.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
