Methemoglobinemia due to p-chloroaniline

Methemoglobinemia is known to occur due to accidental or therapeutic exposure to certain chemicals or drugs that can cause oxidation of the iron of hemoglobin to ferric form. A student of pharmaceutical science developed methemoglobinemia due to accidental exposure to para-chloroaniline during the laboratory experiments. This rare casehighlights the fact that using such laboratory chemicals without proper precautions can be dangerous or even life threatening.
