Chemical Structure

1,4-Dioxocane-5,8-dione CAS 21962-84-5 chemical structure

Description

CATO manufactures 1,4-Dioxocane-5,8-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 1,4-Dioxocane-5,8-dione (CAS 21962-84-5), a certified reference material (molecular formula C6H8O4, MW 144.13 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,4-Dioxocane-5,8-dione is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
