Cinnabarin

Description:
Cinnabarin, with the CAS number 146-90-7, is a chemical compound primarily known for its association with the mineral cinnabar, which is a source of mercury. Cinnabarin is characterized by its bright red color, which is attributed to the presence of mercury sulfide (HgS) in its structure. This compound is often studied for its historical significance in art and pigment production, particularly in traditional Chinese and other cultures where it was used as a pigment for painting and cosmetics. Cinnabarin is insoluble in water but can react with strong acids, releasing mercury ions. Due to the toxicity of mercury and its compounds, cinnabarin poses health risks, necessitating careful handling and disposal. Its use has declined in modern applications due to safety concerns, and it is now primarily of interest in historical and geological studies. Overall, cinnabarin exemplifies the intersection of chemistry, art, and environmental health, highlighting the importance of understanding the properties and risks associated with chemical substances.
