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 Copper(II) phosphate.
Copper(II) phosphate (CAS 7798-23-4) is a high-purity analytical reference standard with the molecular formula Cu3O8P2 and a molecular weight of 380.58 g/mol.
Owing to a phosphate ester group, Copper(II) phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
