A chloride of this element is the primary component of the saturated calomelelectrode.
A mixture of potassium hydroxide and this element's tetra-iodo form is used in a reagent used to detectammonia, named for Nessler. A chloride of this element is the primary component of the saturated calomelelectrode. A compound of this element and zinc is used in a gentle acid-medium reduction commonly appliedafter a Friedel-Crafts acylation. This element's dimethyl form was formerly used as an (*) NMR standard, andis known for seeping through the latex glove of Karen Wetterhan. The acetate of this element is used in a reactionto add an alcohol to an alkene in a Markovnikov fashion.
