If death has a smell, it ought to be like the pungent odor of formaldehyde. In its liquid form called formalin, the organic compound (CH2O) has long been used in mortuaries as well as laboratories to preserve both bodies and individual organs.
The somewhat pale yellow liquid that dead things float in in laboratory jars is formaldehyde. It is ironic that a compound that preserves organs and bodies so well has now been added to the list of known carcinogens by the U.S. government that it says may cause cancer. What it means is that while formaldehyde can kill you, it can also preserve you once it has killed you. If there is a chemical compound more ironic than formaldehyde, I would like to know.
At room temperature formaldehyde is gaseous but it is known as formalin in a liquid form. There is something utterly clinical about the smell of formaldehyde. For a long time the odor used to remind me of something otherworldly as well. There is a reason for that. It seems formaldehyde widely exists in interstellar space. That may explain why I feel the way I feel every time I have encountered formaldehyde smell. I feel as if I am floating around in interstellar space.
The list of carcinogens is always growing and the appearance of formaldehyde is no surprise because it was long suspected to have very harmful effects. There are reports that the chemical industry fought hard to keep it off the list because of its very extensive use in building materials of all kinds.
Incidentally, it is also used in hair straightening products. So next time you seem a woman with unnaturally straight and ironed hair, gabbing away on her cell phone, you know she is tempting fate. For those of you who may not get the connection (no pun intended) mobile phones are also on the list of carcinogens now for their potential to cause cancerous brain tumor because of the radiation.
