It is a corrosive liquid (anhydrous) or solid (hydrated). It makes hydrochloric acid fumes which irritate the nose. It reacts with strong bases to make tin(IV) oxide hydrate. It also reacts with hydrochloric acid to make the SnCl62- ion.
It is made by reacting tin with chlorine.
Sn + 2 Cl2 → SnCl4
It was used in World War I to create irritating clouds of smoke. It is also used to make tin(IV) fluoride. It is also used to make organic compounds that have tin in them.
