Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...
It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs. The list is designated within the Controlled Substances Act [ 1 ] but can be modified by the U.S. Attorney General as illegal manufacturing practices change.
Phosphorus pentasulfide is the inorganic compound with the formula P 2 S 5 or P 4 S 10 . This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon disulfide but reacts with many other solvents such as alcohols, DMSO, and DMF.

Phosphorus forms a wide range of sulfides, where the phosphorus can be in P(V), P(III) or other oxidation states. The three-fold symmetric P 4 S 3 is used in strike-anywhere matches. P 4 S 10 and P 4 O 10 have analogous structures. [48] Mixed oxyhalides and oxyhydrides of phosphorus(III) are almost unknown.

Diphosphorus trisulfide (sometimes called phosphorus trisulfide) is a phosphorus sulfide with the formula of P 2 S 3. The substance is highly unstable and difficult to study. [3] In contrast, the formal dimer P 4 S 6 is well-known.
