Carbon monosulfide · Thiocarbonyl

Carbon monosulfide is a highly reactive chemical species consisting of a carbon atom double-bonded to a sulfur atom. Due to its unstable nature, it is primarily studied in laboratory settings and astrophysical environments rather than being used in bulk industrial applications.
