Cupric nitrate extra pure

Cupric nitrate extra pure, chemically copper(II) nitrate (Cu(NO3)2), is an inorganic blue crystalline solid notable for its strong oxidizing properties and high solubility in water. The compound exists commonly in hydrated forms but also as an anhydrous solid which sublimes in vacuum at 150–200 °C. Its typical molecular weight is about 187.56 g/mol for the anhydrous form.​

Identity and Composition

Chemical name: Copper(II) nitrate or Cupric nitrate.​

Molecular formula: Cu(NO3)2; with common hydrated forms (trihydrate, hexahydrate).​

Appearance: Blue crystalline solid for hydrates; anhydrous form is blue-green crystals.​

Physical Properties

Density: Approximately 3.05 g/cm³ (anhydrous).​

Melting point: Hydrated forms melt around 114.5 °C; anhydrous decomposes at ~256 °C.​

Solubility: Highly soluble in water, ethanol, and ammonia.​

Typical Uses

Cupric nitrate is utilized as a reagent and catalyst in organic synthesis, in the synthesis of copper compounds, fungicides, pyrotechnics, and as a source of copper ions. It decomposes on heating to yield copper oxide and nitrogen oxides, useful industrially for nitric acid production.​

Handling and Safety

It is hygroscopic, toxic if ingested, and an irritant to skin and eyes. It releases toxic nitrogen dioxide gas upon decomposition; proper handling and storage in airtight containers are advised to prevent moisture absorption.​
