They realized that when NIS transports a negatively charged perchlorate ion across a membrane, only one positive sodium accompanies it--instead of the two that NIS transports through with iodine.
Therefore, the perchlorate ion is identical whether derived from potassium, sodium, or ammonium salts.
It is thought that because of its similarity in ionic size to iodide, the perchlorate ion is a competitive inhibitor of iodide at the sodium iodide symporter (NIS), the plasma membrane protein that catalyzes the accumulation of iodide into thyroid cells (Wolff 1998).
The ammonium salt of the perchlorate ion is manufactured primarily for use by the Department of Defense, the National Aeronautics and Space Administration, and the aerospace industry as a source of oxygen in solid propellant systems for rockets and missiles.
