1Iodopentane

1-Iodopentane, also known as n-amyl iodide, is an organic compound with the chemical formula CH3(CH2)4I. It is a primary alkyl halide and a derivative of pentane where a hydrogen atom on the terminal carbon has been replaced by an iodine atom.

In appearance, 1-iodopentane is typically a colorless to pale yellow liquid. It is insoluble in water but miscible with many organic solvents like ethanol and ether. Its molecular weight is approximately 212.05 g/mol. The boiling point of 1-iodopentane is around 178-180 °C, and its melting point is approximately -75 °C.

1-Iodopentane is primarily used as a reagent in organic synthesis. It serves as an alkylating agent, introducing the n-amyl group into other molecules through nucleophilic substitution reactions. For example, it can react with Grignard reagents to form longer chain alkanes or with alkoxides to form ethers. Due to the relatively weak carbon-iodine bond, it is more reactive in such substitution and elimination reactions compared to its bromo- or chloro- counterparts. It can also be a precursor in the synthesis of other pentane derivatives.

The compound should be handled with appropriate safety precautions as it can be an irritant and should be kept away from heat and open flames due to its flammability.
