DMSA is a white crystaline powder with an unpleasant but characteristic mercaptor odour and taste.
It is used to transfer mercury and other heavy metals safely into the urine for excretion. DMSA can cross the blood-brain barrier, and thus is useful for extracting heavy metals from the brain.
DMSA is also called succimer, and is sold under the brand name Chemet®.
