Tin (2+) Oxalate, identified by CAS 814-94-8, is a crystalline inorganic metal salt that functions primarily as a specialized catalyst and reducing agent within industrial chemical synthesis. Recognized across material science sectors as Stannous oxalate, this compound leverages the bivalent state of tin to facilitate complexation and accelerate reaction kinetics in organic environments. In polymer manufacturing, Tin(II) oxalate serves as an essential catalyst for esterification and transesterification workflows, particularly in the production of specialized resins. The textile processing industry typically utilizes Tin ethanedioate as a mordant for fabric dyeing operations, while metallurgical and energy sectors integrate Oxalato tin into coal hydrogenation processes. For procurement requirements, we provide bulk supply capabilities to support continuous manufacturing lines. Our chemical distribution framework accommodates customized specifications based on specific reaction parameters, offering competitive factory pricing for industrial partners. Every shipment is accompanied by comprehensive regulatory and technical documentation, including MSDS, TDS, COA, ensuring full compliance with international safety and quality standards.

Storage & Safety
Tin (2+) Oxalate must be stored in a cool, dry, and well-ventilated warehouse, strictly isolated from strong oxidizing agents and strong acids to prevent degradation. It is sensitive to moisture and prolonged air exposure, which can cause oxidation of the bivalent tin. Personnel handling the bulk powder must use appropriate Personal Protective Equipment (PPE), including NIOSH-approved dust masks, nitrile gloves, and safety goggles, to prevent inhalation of particulates and avoid direct skin or eye contact.
Quality Assurance
To ensure batch-to-batch consistency for industrial applications, our factory implements rigorous quality control protocols. The bivalent tin (Sn2+) active content is precisely quantified using iodometric titration methods, while trace heavy metal impurities are screened via Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). Production workflows adhere to ISO-standard industrial chemical management systems, ensuring material stability and high catalytic activity for downstream synthesis.
FAQ - Technical & Supply Chain
-
Q:
How is the identity and active valence state of this Tin (2+) Oxalate verified?
A: The identity of CAS 814-94-8 is confirmed through its precise tin content (approximately 57%), which is routinely verified via titration to ensure the tin remains strictly in the active +2 oxidation state, distinguishing it from tetravalent impurities. -
Q:
Is Stannous Oxalate intended for use as a primary reducing agent or a catalyst in polymer synthesis?
A: While it possesses inherent reducing properties, it is predominantly applied as an esterification and transesterification catalyst within polymer manufacturing workflows, rather than functioning solely as a bulk reducing agent in these specific processes.
