Stannous oxalate

Stannous oxalate (CAS 814-94-8), also known as tin oxalate, is a tin(II) salt used primarily as a catalyst and catalyst precursor in polymer synthesis and specialty chemical manufacturing.

Where is Stannous oxalate used?

• Plastics and polymer production: catalyzes polycondensation reactions
• Polyesters and biodegradable polymers such as polylactic acid (PLA)
• Personal care: stabilizing and chelating agent that sequesters metal ions
• Pharmaceutical and biotech: tin source in synthesis intermediates
• Radiolabeling processes where controlled tin(II) chemistry is critical
• Water treatment: chelation activity manages trace metal interference in treatment chemical formulations
• It enables controlled reaction pathways in esterification and polycondensation processes.

Commercial specifications

• Technical and high-purity grades
• Packaging from laboratory-scale quantities to bulk industrial supply
