Chemical Structure

Copperoxalate CAS 814-91-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Copperoxalate.

Copperoxalate (CAS 814-91-5) is a high-purity analytical reference standard with the molecular formula C2O4Cu and a molecular weight of 151.56 g/mol.

Owing to a carboxylic acid group, an ether linkage, Copperoxalate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.56 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.

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.
