Tin(IV) chloride pentahydrate is widely used as a catalyst in organic synthesis, particularly in Friedel-Crafts reactions, where it facilitates the alkylation and acylation of aromatic compounds. It is also employed in the production of tin-based coatings and as a precursor for other tin compounds. In the electronics industry, it serves as a key material for chemical vapor deposition (CVD) processes to create tin oxide films, which are essential for manufacturing transparent conductive coatings used in touchscreens and solar panels. Additionally, it is utilized in the textile industry as a mordant to fix dyes onto fabrics, ensuring vibrant and long-lasting colors. Its role in the synthesis of pharmaceuticals and fine chemicals further highlights its versatility in industrial applications.
