Used as a reducing agent in organic synthesis, particularly in the selective reduction of nitro compounds to hydroxylamines and in the dehalogenation of organic halides. It finds application in polymer chemistry for initiating radical reactions and in the preparation of coordination compounds due to its ability to donate electrons. Also utilized in analytical chemistry for the detection and determination of certain metal ions. Its unique trans-configuration enhances stability and reactivity in aqueous solutions, making it suitable for reactions under mild conditions.
