Stannic chloride

Stannic chloride (CAS 7646-78-8), also known as tin tetrachloride or SnCl4, is an inorganic tin compound supplied primarily as a fuming liquid or in hydrated form.

Where is Stannic chloride used?

• Chemical synthesis and polymer production: Lewis acid catalyst and tin source
• Plastics and polymer manufacturing: catalyst and stabilizer precursor in PVC and other tin-stabilized formulations
• Pharmaceutical synthesis: Lewis acid catalyst for Friedel-Crafts reactions and other electrophilic processes
• Indium tin oxide (ITO) coatings and conductive thin films: tin precursor deposited onto glass or plastic substrates for electronics
• Specialty chemical manufacturing: intermediate for producing organotin compounds
• Organotin compounds are frequently used as biocides and stabilizers in industrial formulations and coatings.

Good to know: The hydrated form is preferred where moisture sensitivity is less critical.

Commercial specifications

• Bulk quantities packaged in drums or IBCs
