| Hazard Information | Back Directory | [General Description]
A colorless to yellow-colored liquid with a strong odor. Flash point 90°F. Slightly denser than water and insoluble in water. Vapors heavier than air. May irritate skin and eyes. In high concentrations the vapors may be narcotic. | [Reactivity Profile]
2-BROMOPENTANE(107-81-3) is incompatible with strong oxidizing and reducing agents. Also incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Health Hazard]
Irritating to eyes, nose, throat, and upper respiratory tract. Causes skin irritation. | [Chemical Properties]
2-bromopentane is a colorless to yellow-colored liquid with a strong odor. It is an optically active compound because it contains an asymmetric carbon (chiral carbon). An asymmetric carbon is carbon atom that is attached to four different types of atoms or groups of atoms. In 2-Bromopentance, the central carbon atom is attached to four different types of atoms (CH2, CH3, Br, H), hence it is an optically active compound. | [Uses]
Used as a chemical intermediate. | [Purification Methods]
Dry it over K2CO3 and distil it through a short Vigreux column (p 11). [IR: Pines et al. J Am Chem Soc 74 4063 1952, Brown & Wheeler J Am Chem Soc 78 2199 1956, Beilstein 1 IV 312.] |
