CAS: 12158-75-7
Alias: Copper nitrate basic; Cupric nitrate basic
Molecular formula:CuHNO4(-2)
Relative molecular mass:142.56
Structural formula:
1. Product Property
Basic copper nitrate is a light blue powder with a density of 3.4 g/cm³. It is insoluble in water and alcohol but soluble in dilute acids and ammonia solution. It exhibits strong oxidizing properties and decomposes upon heating to produce copper oxide, nitrogen dioxide, and oxygen. The compound is stable under normal conditions but should be handled with care due to its oxidative nature
2. Quality Standard
| Parameter | Specification |
| Appearance | Light blue powder |
| Copper (Cu) content | 52.5% – 53.6% |
| Nitrate (NO₃⁻) content | 25.3% – 26.3% |
| Moisture | ≤ 0.3% |
| pH (100 g/L solution) | 5.5 – 7.5 |
| Particle size (D50) | ≤ 1.5 μm (for special grade) |
| Sodium (Na) | ≤ 0.5% |
3. Application Scope and Usage
Basic copper nitrate is widely used as a catalyst in organic synthesis reactions, particularly in oxidation processes. It also serves as an effective preservative for wood and textiles due to its antimicrobial and antifungal properties. In materials science, it is used to prepare copper-based intermediates and nanomaterials. Additionally, it is employed in the production of gas-generating compositions for automotive safety systems
4. Package and Storage
Basic copper nitrate is typically packed in 25 kg woven bags with double-layer plastic liners to ensure sealing and moisture resistance. It should be stored in a cool, dry, and well-ventilated warehouse. The packaging must be tightly sealed to prevent moisture ingress. It is essential to avoid contact with acids, combustibles, and reducing agents during storage and transport. The shelf life is generally 24 months under proper storage conditions
