Chemical Structure

Sodium 2-acetamidomalonate CAS 117976-12-2 chemical structure

Description

As a certified reference material (CRM), Sodium 2-acetamidomalonate 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 2-acetamidomalonate (CAS 117976-12-2) is a high-purity analytical reference standard with the molecular formula C5H5NNa2O5 and a molecular weight of 205.08 g/mol.

Owing to a carbohydrate-derived structure, an amide group, Sodium 2-acetamidomalonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.08 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.
