A dark compound derived from hemoglobin that contains iron and is used in biochemistry and forensics.
From 'haema' (blood) + the chemical suffix '-in'. Scientists isolated this iron-containing compound from blood in the 19th century and named it based on its source.
Haemin creates a striking blue color in a famous forensic test called the Takayama test—crime scene investigators use it to detect bloodstains invisible to the naked eye.
