Chemical Structure

4,5-Dioxopentanenitrile CAS 876501-78-9 chemical structure

Description

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.

4,5-Dioxopentanenitrile (CAS 876501-78-9), molecular formula C5H5NO2 and molecular weight 111.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4,5-Dioxopentanenitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 111.10 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.
