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.
Nickel(II) peroxide hydrate (CAS 86676-91-7), molecular formula NiO2H2O and molecular weight 108.71 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an inorganic composition, Nickel(II) peroxide hydrate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
