2iodoethanol

2-Iodoethanol is an organic compound with the formula C2H5IO. It is a colorless to slightly yellow liquid with a characteristic odor. It is a derivative of ethanol, with an iodine atom replacing one of the hydrogen atoms on the ethanol molecule. The compound is used as a reagent in organic synthesis, particularly in the synthesis of certain pharmaceuticals and agrochemicals.

2-Iodoethanol is prepared by the reaction of ethanol with iodine in the presence of a catalyst such as iron(III) chloride. The reaction proceeds via a radical chain mechanism, where iodine abstracts a hydrogen atom from ethanol to form 2-iodoethanol and hydrogen iodide.

The compound is highly reactive due to the presence of the iodine atom, which can undergo nucleophilic substitution reactions. It is used in the synthesis of various compounds, including 2-iodoethanol itself, which can be further reacted to form other iodoalkanes.

2-Iodoethanol is toxic if swallowed and may cause skin irritation. It is also corrosive to metals and can react violently with strong oxidizing agents. Therefore, it should be handled with care, using appropriate personal protective equipment and in a well-ventilated area.

The compound is not widely used in industry due to its high cost and the availability of more efficient and selective reagents. However, it remains an important reagent in academic research and specialized applications.
