2-Bromo-2-methylpropane
Systematic nomenclature: 2-bromo-2-methylpropane
Common names: Bromoisobutane, tert-butyl bromide, trimethyl bromide
Molecular formula: C4H9Br
Molecular weight: 137.02 g/mol
CAS: 507-19-7
Appearance: Colorless to pale yellow transparent liquid. Pure products are usually colorless, but they may turn slightly yellow due to decomposition if left for a long time or exposed to light.
Odor: It has a special pungent odor.
Boiling point: 73.1 °C (163.6 °F) - This is one of its notable features, with a relatively low boiling point.
Melting point: -16.3 °C (2.7 °F)
Density: approximately 1.26 g/cm³ (at 20°C) - heavier than water.
Refractive index (nD²⁰) : approximately 1.428
Solubility: Slightly soluble in water. It is readily soluble in most organic solvents, such as ethanol, ether, acetone, benzene, chloroform, etc. Miscible with hydrocarbon solvents.
Flash point: Approximately 18°C (64°F) - Flammable liquid.
Stability: Relatively unstable, especially sensitive to light and heat. It is prone to elimination reactions (debromination of hydrogen bromide) or hydrolysis under alkaline conditions or when heated. A small amount of stabilizer (such as silver or copper shavings) is often added to pure products to slow down decomposition.
