Its EINECS registry number is 202-716-0. This chemical's molecular formula is C₆H₅NO₂ and molecular weight is 123.11. What's more, its IUPAC name is the same with its product name. Nitrobenzene is a water-insoluble pale yellow oil with an almond-like odor. This chemical freezes to give greenish-yellow crystals. It should be stored in a cool, dry and well-ventilated place.

Physical properties about Nitrobenzene are: (1)ACD/LogP: 1.92; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 1.921; (4)ACD/LogD (pH 7.4): 1.921; (5)ACD/BCF (pH 5.5): 16.986; (6)ACD/BCF (pH 7.4): 16.986; (7)ACD/KOC (pH 5.5): 264.311; (8)ACD/KOC (pH 7.4): 264.311; (9)#H bond acceptors: 3; (10)#H bond donors: 0; (11)#Freely Rotating Bonds: 1; (12)Polar Surface Area: 45.82 Å²; (13)Index of Refraction: 1.561; (14)Molar Refractivity: 32.798 cm³; (15)Molar Volume: 101.275 cm³; (16)Surface Tension: 45.313 dyne/cm; (17)Density: 1.216 g/cm³; (18)Flash Point: 81.413 °C; (19)Enthalpy of Vaporization: 42.885 kJ/mol; (20)Boiling Point: 210.799 °C at 760 mmHg; (21)Vapour Pressure: 0.274 mmHg at 25 °C.

Preparation of Nitrobenzene: this chemical can be prepared by 4-Nitro-benzenediazonium; chloride. This reaction needs reagents water, phosphinic acid at temperature of 0 °C.

Uses of Nitrobenzene: (1) it is used as a solvent and a flavoring or perfume additive; (2) it is used to produce other chemicals. For example, it can react with 2-Amino-benzoic acid to get Phenazine-1-carboxylic acid. The reaction occurs with reagent KOH at temperature of 145 - 160 °C.

When you are dealing with this chemical, you should be very careful. This chemical may cause damage to health and present an immediate or delayed danger to one or more components of the environment. It may catch fire in contact with air, only need brief contact with an ignition source and have a very low flash point or evolve highly flammable gases in contact with water. In addition, it has danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. The production is toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment. Therefore, you should keep container tightly closed and you should wear suitable protective clothing and gloves. What's more, you must keep away from sources of ignition and avoid releasing to the environment. In case of accident or if you feel unwell seek medical advice immediately.
