Chlormerodrin
Chlormerodrin is urea in which one of the hydrogens is substituted by a 3-chloromercury-2-methoxyprop-1-yl group. It was formerly used as a diuretic, but more potent and less toxic drugs are now available. Its radiolabelled ((197)Hg, (203)Hg) forms were used in diagnostic aids in renal imaging and brain scans. It has a role as a diuretic and a diagnostic agent. It is an organomercury compound and a member of ureas.
