Product Description

Ethyl triphenyl phosphonium iodide (ETI) is a quaternary ammonium salt with the chemical formula (C6H5)3PCH2CH3I. It is a white or off-white crystalline solid that is soluble in organic solvents like ethanol, acetone, and dichloromethane. ETI is commonly used as a Wittig reagent in organic synthesis.

In organic synthesis, ETI is used as a Wittig reagent to convert carbonyl compounds, such as aldehydes and ketones, into alkenes. The reaction between ETI and the carbonyl compound results in the formation of a ylide intermediate, which then reacts with an electrophilic reagent to produce an alkene. This reaction is useful in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals.

ETI is generally considered safe to handle and use, but it can be an irritant if it comes into contact with skin or eyes. Protective equipment like gloves and safety glasses should be worn when handling ETI. Additionally, it should be stored in a cool, dry place away from sources of heat and flame.
