SnCl4, or tin(IV) chloride, is a chemical compound made up of one tin (Sn) atom and four chlorine (Cl) atoms. It appears as a colorless, hygroscopic solid that can dissolve in water and organic solvents. SnCl4 is commonly used in various industrial applications, including as a catalyst in chemical reactions and in the production of organotin compounds. In addition to its industrial uses, SnCl4 plays a role in organic synthesis, particularly in the formation of certain types of organic compounds. It can also be used in the preparation of other tin compounds and as a reagent in laboratory settings. Proper handling is essential, as SnCl4 can be corrosive and harmful if inhaled or ingested.
