: It acts as an expectorant in cough remedies by irritating the gastric mucosa, which stimulates respiratory tract fluid production to loosen mucus.
: This taste likely evolved as a survival mechanism to help animals and humans avoid consuming decaying organic matter or waste, where high levels of ammonium are common.
: In conservation science, it is used in electrolytic reduction to remove corrosion from ancient metal artifacts.

: Despite being a "warning" taste, it is a hallmark of Nordic salty licorice ( salmiakki ), where it provides a distinctive sharp, stinging sensation. Medical and Physiological Effects
Recent scientific studies have proposed that ammonium chloride may represent a , joining sweet, sour, salty, bitter, and umami. : It acts as an expectorant in cough
Beyond its role in taste, ammonium chloride has significant systemic impacts on the body:
: Researchers at the University of Southern California identified that the OTOP1 protein channel—originally known as a sour taste receptor—is uniquely activated by ammonium chloride. : In highly polluted urban environments like Delhi,
: In highly polluted urban environments like Delhi, ammonium chloride has been identified as the largest contributor to aerosol liquid water , making up roughly 40% of the water content that exacerbates haze and reduces visibility.
