Chemical Structure

Sodium (Z)-1,4-diethoxy-1,4-dioxobut-2-en-2-olate CAS 88330-76-1 chemical structure

Description

As a certified reference material (CRM), Sodium (Z)-1,4-diethoxy-1,4-dioxobut-2-en-2-olate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Sodium (Z)-1,4-diethoxy-1,4-dioxobut-2-en-2-olate (CAS 88330-76-1) is a high-purity analytical reference standard with the molecular formula C8H11NaO5 and a molecular weight of 210.16 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Sodium (Z)-1,4-diethoxy-1,4-dioxobut-2-en-2-olate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.16 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).

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