C3O2

C3O2, also known as carbonyl cyanide, is a colorless liquid with a pungent odor. Its chemical formula is C3N2O. It is a highly reactive and toxic compound. C3O2 is considered a chemical weapon precursor and is listed on Schedule 3 of the Chemical Weapons Convention. Its synthesis and possession are strictly controlled by international treaties.

The compound can be produced through the reaction of malononitrile with an oxidizing agent. C3O2 is unstable and tends to polymerize, especially in the presence of moisture or heat. It is soluble in organic solvents such as ether and chloroform. Due to its toxicity and reactivity, C3O2 is handled with extreme caution in laboratory settings.

Historically, carbonyl cyanide was explored for its potential use in chemical warfare, leading to its classification and regulation. Its properties make it a significant concern for global security, necessitating rigorous monitoring and control of its production and distribution. Research into its chemical behavior continues, primarily for understanding its hazards and developing countermeasures. The industrial applications of C3O2 are very limited due to its inherent dangers.
