Specification

The Cobalt nitrate, with the CAS registry number 10141-05-6 and EINECS registry number 231-158-0, has the systematic name of cobalt(2+) dinitrate. It is a kind of is the inorganic cobalt(II) salt of nitric acid with the apperance of odorless red solid, and it is more commonly found as a hexahydrate. And the molecular formula of this chemical is CoH₂N₂O₆.

The physical properties of Cobalt nitrate are as following: (1)ACD/LogP: -0.13; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -0.13; (4)ACD/LogD (pH 7.4): -0.13; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 4; (8)#H bond donors: 1; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 66.05 Å²; (11)Enthalpy of Vaporization: 37.72 kJ/mol; (12)Boiling Point: 83 °C at 760 mmHg; (13)Vapour Pressure: 49.8 mmHg at 25°C.

Preparation of Cobalt nitrate: It is commonly found as hexahydrate, Co(NO₃)₂^.6H₂O. And the hexahydrate derived from reacting metallic cobalt or one of its oxides, hydroxides, or carbonate with nitric acid. And when the temperature is higher than 55 °C, it will dehydrate to the trihydrate and at a higher temperature to the anhydrous.
CoCO₃ + 2 HNO₃ + 5 H₂O → Co(NO₃)₂(H₂O)₆ + CO₂

Uses of Cobalt nitrate: Because of its high solubility, it becames a common source of cobalt in metal-organic frameworks and coordination chemistry. It is also reduced to metallic cobalt or precipitated on various substrates for Fischer-Tropsch catalysis. What's more, it is also used in dyes and inks.

You should be cautious while dealing with this chemical. It is a kind of irritant chemical which may cause cancer. It is very toxic to aquatic organisms, and may cause long-term adverse effects in the aquatic environment. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; Avoid exposure - obtain special instruction before use; Do not breathe gas/fumes/vapor/spray (appropriate wording to be specified by the manufacturer); Avoid release to the environment. Refer to special instructions safety data sheet; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).

You can still convert the following datas into molecular structure:
(1)SMILES: [Co+2].[O-][N+]([O-])=O.[O-][N+]([O-])=O
(2)InChI: InChI=1/Co.2NO3/c;2*2-1(3)4/q+2;2*-1
(3)InChIKey: UFMZWBIQTDUYBN-UHFFFAOYAS
