Specification

The Methyl bromide is an organic compound with the formula CH3Br. The IUPAC name of this chemical is bromomethane. With the CAS registry number 74-83-9, it is also named as DL-Methylbromide. The product's category is Organics. Besides, it is colourless gas with a chloroform-like odour.

The Methyl bromide is a recognized ozone-depleting chemical. It is used extensively as a pesticide. It is widely applied as a soil sterilant, mainly for production of seed but also for some crops such as strawberries and almonds. The Methyl bromide is also a precursor in the manufacture of other chemicals as a methylating agent, and has been used as a solvent to extract oil from seeds and wool.

Physical properties about Methyl bromide are: (1)ACD/LogP: 1.15; (2)ACD/LogD (pH 5.5): 1.15; (3)ACD/LogD (pH 7.4): 1.15; (4)ACD/BCF (pH 5.5): 4.39; (5)ACD/BCF (pH 7.4): 4.39; (6)ACD/KOC (pH 5.5): 100.36; (7)ACD/KOC (pH 7.4): 100.36; (8)Index of Refraction: 1.409; (9)Molar Refractivity: 14.41 cm3; (10)Molar Volume: 58.2 cm3; (11)Polarizability: 5.71×10-24cm3; (12)Surface Tension: 20.6 dyne/cm; (13)Density: 1.63 g/cm3; (14)Enthalpy of Vaporization: 23.91 kJ/mol; (15)Boiling Point: 3.8 °C at 760 mmHg; (16)Vapour Pressure: 1590 mmHg at 25°C.

Preparation: this chemical can be prepared by methanol. This reaction will need reagent naphthalene and bromine.



Uses of Methyl bromide: it can be used to produce 1,4-dimethyl-pyridinium; bromide by heating. It will need reagent ethanol with reaction time of 10 hours.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and harmful by inhalation and if swallowed. It is toxic by inhalation and if swallowed and danger of serious damage to health by prolonged exposure through inhalation. Please keep container tightly closed, keep away from heat and keep away from sources of ignition - No smoking.
