Chemical Structure

Copper(II) L-tartrate hydrate CAS 55326-78-8 chemical structure

Description

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

Copper(II) L-tartrate hydrate (CAS 55326-78-8), molecular formula C4H4O6CuH2O and molecular weight 229.63 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Copper(II) L-tartrate hydrate (C4H4O6CuH2O) is characterized by a carbohydrate-derived structure. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
