Formula & Molecular Weight	SnC₂O₄(MW: 206.73) \| EC: 212-414-0
Chemical Structure
Product Type	Tin(II) Salt / Esterification Catalyst / Textile Processing Auxiliary Stannous Oxalate is a solid tin(II) salt used as a catalyst in esterification, selected polyester and polycondensation processes, and in certain textile dyeing and printing applications.
Typical Specification	Appearance: White powder Assay (as SnC₂O₄): ≥99.0%
Reference Properties	Physical State: Solid powder Density: Approx. 3.56 g/cm³ at 20°C Water Solubility: Insoluble in water Theoretical Tin Content: Approx. 57.42% for pure SnC₂O₄ The values above are provided for product identification and application reference only. The theoretical tin content is a calculated value and is not a fixed Royalchem batch-release specification.
Key Applications	Stannous Oxalate is used as a tin-based catalyst for esterification, selected polyester and polycondensation processes, as well as in certain textile processing applications. Esterification Catalyst: Used in esterification reactions between carboxylic acids and alcohols, including selected high-boiling esters, plasticizers and specialty esters. Polyester and Polycondensation: Used as a catalyst in selected polyester, resin and other polycondensation systems. Suitability depends on the raw materials, process conditions and required final-product properties. Polymer Processing: May be used as a tin catalyst in selected polymer preparation processes. Catalyst loading should be determined through process testing. Textile Dyeing and Printing: Used in certain textile dyeing and printing processes. Application performance should be evaluated according to the specific dye, fiber and production system.
Packaging, Storage & Shipping	Packaging: Sealed, moisture-resistant commercial packaging is selected according to product grade, order quantity and shipping requirements. Final package type and net weight are confirmed with the commercial order. Storage: Store in a cool, dry and well-ventilated area. Keep containers tightly closed and protect the product from moisture. Reseal promptly after sampling or use. Handling and Shipping: Avoid generating or inhaling dust and use appropriate personal protective equipment in accordance with the applicable SDS. Hazard classification, shipping conditions and regulatory requirements are subject to the SDS and transport assessment for the actual supplied product.

Main Application Areas of Stannous Oxalate

Esterification and Specialty Esters	Used as a tin catalyst for reactions between carboxylic acids and alcohols, including selected plasticizers, high-boiling esters and specialty ester products.
Polyester and Polycondensation	Used in selected polyester and resin processes. Performance depends on raw-material composition, reaction temperature, moisture level, target acid value and final-product requirements.
Textile Dyeing and Printing	Used in certain textile dyeing and printing processes. Customers should evaluate compatibility with the specific dye system, fiber type and process conditions.
Process Validation	Recommended catalyst loading cannot be generalized across all applications. Laboratory trials and process scale-up validation are recommended before commercial production.

Key Purchasing Considerations

Item	What to Confirm
Assay	Confirm the assay basis, analytical method and whether the result is calculated as SnC₂O₄.
Tin Content	Pure SnC₂O₄ has a theoretical tin content of approximately 57.42%. Actual batch results depend on assay and analytical method.
Metal Impurities	Customers with color-sensitive, polymer or high-specification applications should state required limits for iron, lead, copper, zinc or other relevant impurities.
Particle Size and Dispersibility	If feeding rate, dispersion or filtration performance is important, provide the target particle-size or process requirements with the inquiry.
Documentation and Packaging	Confirm required COA, SDS, package size, label language, destination country and shipping requirements before order placement.

Frequently Asked Questions

What is CAS 814-94-8?	CAS 814-94-8 is Stannous Oxalate, also known as Tin(II) Oxalate. Its molecular formula is SnC₂O₄.
