title: Identification of an imidazolinium salt, the major product from reaction of benzathine with iodine.
abstract: The isolation and identification of an imidazolinium salt are described. Unambiguous determination of structure was accomplished by independent synthesis. The isolated product interferes in the iodometric assay of the benzathine salts of penicillin.
