There are many.
Polymers (and all of their uses)
Drugs
Explosives - Just about any explosive is relevant
Food additives - EDTA chelates iron in ketchup, so that you don't get a bitter taste when you eat stuff with it.
Forensics - Luminol is a material that glows in the presence of iron, so it can detect blood by attaching to the homoglobin, another is ninhydrin, the material that's used to detect fingerprints

it needs a lot of work but i think its nice
