Chemical Structure

Copper nitrate trihydrate CAS 10031-43-3 chemical structure

Description

The occurrence of Copper nitrate trihydrate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Copper nitrate trihydrate (CAS 10031-43-3), a certified reference material (molecular formula CuNO3H2O, MW 143.56 g/mol) for analytical method development and quality control.

Based on its molecular formula CuNO3H2O, Copper nitrate trihydrate contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 143.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
