• Canonical SMILES: [N+](=O)([O-])[O-].[N+](=O)([O-])[O-].[Co+2]
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. Ingestion may cause effects on the bone marrow, heart and thyroid. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
• Uses: Cobalt nitrate is used in the decoration of porcelain and stones; in the manufacture of invisible inks and cobalt pigments; in hair dyes; in animal feeds; as an additive to soils; in catalysts preparation; and in vitamin supplements. Sympathetic inks, cobalt pigments, catalysts, additive to soils and animal feeds, vitamin preparations, hair dyes, porcelain decoration. Cobalt(II) Dinitrate is mainly reduced to metallic high purity cobalt used for catalysis reactions.
• Physical properties: The hexahydrate is red monoclinic crystal; deliquescent in moist air; density 1.87 g/cm3; decomposes at 55°C, losing three molecules of water; decomposes to green cobalt(II) oxide on further heating at 74°C; very soluble in water (134 g/100mL at 0°C); also soluble in alcohols and acetone. The anhydrous salt is pale red powder; density 2.49 g/cm3; decomposes around 100°C; soluble in water.
